+#  OS/2 specific Makefile for the EMX environment
+#
+#  You need GNU Make 3.71, gcc 2.5.7, emx 0.8h and GNU fileutils 3.9
+#  or similar tools. C++ interface and de.exe weren't tested.
+#
+#  Rename this file "Makefile".
+#
+
+# Primary targets:
+# gc.a - builds basic library
+# c++ - adds C++ interface to library and include directory
+# cords - adds cords (heavyweight strings) to library and include directory
+# test - prints porting information, then builds basic version of gc.a, and runs
+#        some tests of collector and cords.  Does not add cords or c++ interface to gc.a
+# cord/de.exe - builds dumb editor based on cords.
+CC= gcc
+CXX=g++
+# Needed only for "make c++", which adds the c++ interface
+
+CFLAGS= -O -DALL_INTERIOR_POINTERS -DSILENT
+# Setjmp_test may yield overly optimistic results when compiled
+# without optimization.
+# -DSILENT disables statistics printing, and improves performance.
+# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
+#   altered stubborn objects, at substantial performance cost.
+# -DFIND_LEAK causes the collector to assume that all inaccessible
+#   objects should have been explicitly deallocated, and reports exceptions
+# -DSOLARIS_THREADS enables support for Solaris (thr_) threads.
+#   (Clients should also define SOLARIS_THREADS and then include
+#   gc.h before performing thr_ or GC_ operations.)
+# -DALL_INTERIOR_POINTERS allows all pointers to the interior
+#   of objects to be recognized.  (See gc_private.h for consequences.)
+# -DSMALL_CONFIG tries to tune the collector for small heap sizes,
+#   usually causing it to use less space in such situations.
+#   Incremental collection no longer works in this case.
+# -DDONT_ADD_BYTE_AT_END is meaningful only with
+#   -DALL_INTERIOR_POINTERS.  Normally -DALL_INTERIOR_POINTERS
+#   causes all objects to be padded so that pointers just past the end of
+#   an object can be recognized.  This can be expensive.  (The padding
+#   is normally more than one byte due to alignment constraints.)
+#   -DDONT_ADD_BYTE_AT_END disables the padding.

+# To build the thread-safe collector on Tru64, add to the above:
+# -pthread -DGC_OSF1_THREADS
+
+# HOSTCC and HOSTCFLAGS are used to build executables that will be run as

+# For dynamic library builds, it may be necessary to add flags to generate

+
+# Setjmp_test may yield overly optimistic results when compiled
+# without optimization.
+
+# These define arguments influence the collector configuration:
+# -DSILENT disables statistics printing, and improves performance.
+# -DFIND_LEAK causes GC_find_leak to be initially set.
+#   This causes the collector to assume that all inaccessible
+#   objects should have been explicitly deallocated, and reports exceptions.
+#   Finalization and the test program are not usable in this mode.
+# -DGC_SOLARIS_THREADS enables support for Solaris (thr_) threads.
+#   (Clients should also define GC_SOLARIS_THREADS and then include
+#   gc.h before performing thr_ or dl* or GC_ operations.)
+#   Must also define -D_REENTRANT.
+# -DGC_SOLARIS_PTHREADS enables support for Solaris pthreads.
+#   (Internally this define GC_SOLARIS_THREADS as well.)
+# -DGC_IRIX_THREADS enables support for Irix pthreads.  See README.irix.
+# -DGC_HPUX_THREADS enables support for HP/UX 11 pthreads.
+#   Also requires -D_REENTRANT or -D_POSIX_C_SOURCE=199506L. See README.hp.
+# -DGC_LINUX_THREADS enables support for Xavier Leroy's Linux threads.
+#   see README.linux.  -D_REENTRANT may also be required.
+# -DGC_OSF1_THREADS enables support for Tru64 pthreads.
+# -DGC_FREEBSD_THREADS enables support for FreeBSD pthreads.
+#   Appeared to run into some underlying thread problems.
+# -DGC_DARWIN_THREADS enables support for Mac OS X pthreads.
+# -DGC_AIX_THREADS enables support for IBM AIX threads.
+# -DGC_DGUX386_THREADS enables support for DB/UX on I386 threads.
+#   See README.DGUX386.
+# -DGC_WIN32_THREADS enables support for win32 threads.  That makes sense
+#   for this Makefile only under Cygwin.
+# -DGC_THREADS should set the appropriate one of the above macros.
+#   It assumes pthreads for Solaris.
+# -DALL_INTERIOR_POINTERS allows all pointers to the interior
+#   of objects to be recognized.  (See gc_priv.h for consequences.)
+#   Alternatively, GC_all_interior_pointers can be set at process
+#   initialization time.
+# -DSMALL_CONFIG tries to tune the collector for small heap sizes,
+#   usually causing it to use less space in such situations.
+#   Incremental collection no longer works in this case.
+# -DLARGE_CONFIG tunes the collector for unusually large heaps.
+#   Necessary for heaps larger than about 500 MB on most machines.
+#   Recommended for heaps larger than about 64 MB.
+# -DDONT_ADD_BYTE_AT_END is meaningful only with -DALL_INTERIOR_POINTERS or
+#   GC_all_interior_pointers = 1.  Normally -DALL_INTERIOR_POINTERS
+#   causes all objects to be padded so that pointers just past the end of
+#   an object can be recognized.  This can be expensive.  (The padding
+#   is normally more than one byte due to alignment constraints.)
+#   -DDONT_ADD_BYTE_AT_END disables the padding.
+# -DNO_SIGNALS does not disable signals during critical parts of
+#   the GC process.  This is no less correct than many malloc 
+#   implementations, and it sometimes has a significant performance
+#   impact.  However, it is dangerous for many not-quite-ANSI C
+#   programs that call things like printf in asynchronous signal handlers.
+#   This is on by default.  Turning it off has not been extensively tested with
+#   compilers that reorder stores.  It should have been.
+# -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not
+#   have execute permission, i.e. it may be impossible to execute
+#   code from the heap.  Currently this only affects the incremental
+#   collector on UNIX machines.  It may greatly improve its performance,
+#   since this may avoid some expensive cache synchronization.
+# -DGC_NO_OPERATOR_NEW_ARRAY declares that the C++ compiler does not support
+#   the  new syntax "operator new[]" for allocating and deleting arrays.
+#   See gc_cpp.h for details.  No effect on the C part of the collector.
+#   This is defined implicitly in a few environments.  Must also be defined
+#   by clients that use gc_cpp.h.
+# -DREDIRECT_MALLOC=X causes malloc to be defined as alias for X.
+#   Unless the following macros are defined, realloc is also redirected
+#   to GC_realloc, and free is redirected to GC_free.
+#   Calloc and strdup are redefined in terms of the new malloc.  X should
+#   be either GC_malloc or GC_malloc_uncollectable, or
+#   GC_debug_malloc_replacement.  (The latter invokes GC_debug_malloc
+#   with dummy source location information, but still results in
+#   properly remembered call stacks on Linux/X86 and Solaris/SPARC.
+#   It requires that the following two macros also be used.)
+#   The former is occasionally useful for working around leaks in code
+#   you don't want to (or can't) look at.  It may not work for
+#   existing code, but it often does.  Neither works on all platforms,
+#   since some ports use malloc or calloc to obtain system memory.
+#   (Probably works for UNIX, and win32.)  If you build with DBG_HDRS_ALL,
+#   you should only use GC_debug_malloc_replacement as a malloc
+#   replacement.
+# -DREDIRECT_REALLOC=X causes GC_realloc to be redirected to X.
+#   The canonical use is -DREDIRECT_REALLOC=GC_debug_realloc_replacement,
+#   together with -DREDIRECT_MALLOC=GC_debug_malloc_replacement to
+#   generate leak reports with call stacks for both malloc and realloc.
+#   This also requires the following:
+# -DREDIRECT_FREE=X causes free to be redirected to X.  The
+#   canonical use is -DREDIRECT_FREE=GC_debug_free.
+# -DIGNORE_FREE turns calls to free into a noop.  Only useful with
+#   -DREDIRECT_MALLOC.
+# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
+#   Reduces code size slightly at the expense of debuggability.
+# -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of
+#   order by specifying a nonstandard finalization mark procedure  (see
+#   finalize.c).  Objects reachable from finalizable objects will be marked
+#   in a sepearte postpass, and hence their memory won't be reclaimed.
+#   Not recommended unless you are implementing a language that specifies
+#   these semantics.  Since 5.0, determines only only the initial value
+#   of GC_java_finalization variable.
+# -DFINALIZE_ON_DEMAND causes finalizers to be run only in response
+#   to explicit GC_invoke_finalizers() calls.
+#   In 5.0 this became runtime adjustable, and this only determines the
+#   initial value of GC_finalize_on_demand.
+# -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable.
+#   This is useful if either the vendor malloc implementation is poor,
+#   or if REDIRECT_MALLOC is used.
+# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
+#   sets the heap block size.  Each heap block is devoted to a single size and
+#   kind of object.  For the incremental collector it makes sense to match
+#   the most likely page size.  Otherwise large values result in more
+#   fragmentation, but generally better performance for large heaps.
+# -DUSE_MMAP use MMAP instead of sbrk to get new memory.
+#   Works for Solaris and Irix.
+# -DUSE_MUNMAP causes memory to be returned to the OS under the right
+#   circumstances.  This currently disables VM-based incremental collection.
+#   This is currently experimental, and works only under some Unix,
+#   Linux and Windows versions.
+# -DMMAP_STACKS (for Solaris threads) Use mmap from /dev/zero rather than
+#   GC_scratch_alloc() to get stack memory.
+# -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever
+#   the garbage collector detects a value that looks almost, but not quite,
+#   like a pointer, print both the address containing the value, and the
+#   value of the near-bogus-pointer.  Can be used to identifiy regions of
+#   memory that are likely to contribute misidentified pointers.
+# -DKEEP_BACK_PTRS Add code to save back pointers in debugging headers
+#   for objects allocated with the debugging allocator.  If all objects
+#   through GC_MALLOC with GC_DEBUG defined, this allows the client
+#   to determine how particular or randomly chosen objects are reachable
+#   for debugging/profiling purposes.  The gc_backptr.h interface is
+#   implemented only if this is defined.
+# -DGC_ASSERTIONS Enable some internal GC assertion checking.  Currently
+#   this facility is only used in a few places.  It is intended primarily
+#   for debugging of the garbage collector itself, but could also
+# -DDBG_HDRS_ALL Make sure that all objects have debug headers.  Increases
+#   the reliability (from 99.9999% to 100% mod. bugs) of some of the debugging
+#   code (especially KEEP_BACK_PTRS).  Makes -DSHORT_DBG_HDRS possible.
+#   Assumes that all client allocation is done through debugging
+#   allocators.
+# -DSHORT_DBG_HDRS Assume that all objects have debug headers.  Shorten
+#   the headers to minimize object size, at the expense of checking for
+#   writes past the end of an object.  This is intended for environments
+#   in which most client code is written in a "safe" language, such as
+#   Scheme or Java.  Assumes that all client allocation is done using
+#   the GC_debug_ functions, or through the macros that expand to these,
+#   or by redirecting malloc to GC_debug_malloc_replacement.
+#   (Also eliminates the field for the requested object size.)
+#   occasionally be useful for debugging of client code.  Slows down the
+#   collector somewhat, but not drastically.
+# -DSAVE_CALL_COUNT=<n> Set the number of call frames saved with objects
+#   allocated through the debugging interface.  Affects the amount of
+#   information generated in leak reports.  Only matters on platforms
+#   on which we can quickly generate call stacks, currently Linux/(X86 & SPARC)
+#   and Solaris/SPARC and platforms that provide execinfo.h.
+#   Default is zero.  On X86, client
+#   code should NOT be compiled with -fomit-frame-pointer.
+# -DSAVE_CALL_NARGS=<n> Set the number of functions arguments to be
+#   saved with each call frame.  Default is zero.  Ignored if we
+#   don't know how to retrieve arguments on the platform.
+# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
+#   altered stubborn objects, at substantial performance cost.
+#   Use only for debugging of the incremental collector.
+# -DGC_GCJ_SUPPORT includes support for gcj (and possibly other systems
+#   that include a pointer to a type descriptor in each allocated object).
+#   Building this way requires an ANSI C compiler.
+# -DUSE_I686_PREFETCH causes the collector to issue Pentium III style
+#   prefetch instructions.  No effect except on X86 Linux platforms.
+#   Assumes a very recent gcc-compatible compiler and assembler.
+#   (Gas prefetcht0 support was added around May 1999.)
+#   Empirically the code appears to still run correctly on Pentium II
+#   processors, though with no performance benefit.  May not run on other
+#   X86 processors?  In some cases this improves performance by
+#   15% or so.
+# -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style
+#   prefetch instructions.  Same restrictions as USE_I686_PREFETCH.
+#   Minimally tested.  Didn't appear to be an obvious win on a K6-2/500.
+# -DUSE_PPC_PREFETCH causes the collector to issue PowerPC style
+#   prefetch instructions.  No effect except on PowerPC OS X platforms.
+#   Performance impact untested.
+# -DGC_USE_LD_WRAP in combination with the old flags listed in README.linux
+#   causes the collector some system and pthread calls in a more transparent
+#   fashion than the usual macro-based approach.  Requires GNU ld, and
+#   currently probably works only with Linux.
+# -DTHREAD_LOCAL_ALLOC defines GC_local_malloc(), GC_local_malloc_atomic()
+#   and GC_local_gcj_malloc().  Needed for gc_gcj.h interface.  These allocate
+#   in a way that usually does not involve acquisition of a global lock.
+#   Currently works only on platforms such as Linux which use pthread_support.c.
+#   Recommended for multiprocessors.
+# -DUSE_COMPILER_TLS causes thread local allocation to use compiler-supported
+#   "__thread" thread-local variables.  This is the default in HP/UX.  It
+#   may help performance on recent Linux installations.  (It failed for
+#   me on RedHat 8, but appears to work on RedHat 9.)
+# -DPARALLEL_MARK allows the marker to run in multiple threads.  Recommended
+#   for multiprocessors.  Currently requires Linux on X86 or IA64, though
+#   support for other Posix platforms should be fairly easy to add,
+#   if the thread implementation is otherwise supported.
+# -DNO_GETENV prevents the collector from looking at environment variables.
+#   These may otherwise alter its configuration, or turn off GC altogether.
+#   I don't know of a reason to disable this, except possibly if the
+#   resulting process runs as a privileged user?
+# -DUSE_GLOBAL_ALLOC.  Win32 only.  Use GlobalAlloc instead of
+#   VirtualAlloc to allocate the heap.  May be needed to work around
+#   a Windows NT/2000 issue.  Incompatible with USE_MUNMAP.
+#   See README.win32 for details.
+# -DMAKE_BACK_GRAPH. Enable GC_PRINT_BACK_HEIGHT environment variable.
+#   See README.environment for details.  Experimental. Limited platform
+#   support.  Implies DBG_HDRS_ALL.  All allocation should be done using
+#   the debug interface.
+# -DSTUBBORN_ALLOC allows allocation of "hard to change" objects, and thus
+#   makes incremental collection easier.  Was enabled by default until 6.0.
+#   Rarely used, to my knowledge.
+# -DHANDLE_FORK attempts to make GC_malloc() work in a child process fork()ed
+#   from a multithreaded parent.  Currently only supported by pthread_support.c.
+#   (Similar code should work on Solaris or Irix, but it hasn't been tried.)
+# -DTEST_WITH_SYSTEM_MALLOC causes gctest to allocate (and leak) large chunks
+#   of memory with the standard system malloc.  This will cause the root
+#   set and collected heap to grow significantly if malloced memory is
+#   somehow getting traced by the collector.  This has no impact on the
+#   generated library; it only affects the test.
+# -DPOINTER_MASK=0x... causes candidate pointers to be ANDed with the
+#   given mask before being considered.  If either this or the following
+#   macro is defined, it will be assumed that all pointers stored in

+# This is the original manually generated Makefile.  It may still be used
+# to build the collector.
+#
+# Primary targets:
+# gc.a - builds basic library
+# c++ - adds C++ interface to library
+# cords - adds cords (heavyweight strings) to library
+# test - prints porting information, then builds basic version of gc.a,
+#      	 and runs some tests of collector and cords.  Does not add cords or
+#	 c++ interface to gc.a
+# cord/de - builds dumb editor based on cords.
+ABI_FLAG= 
+# ABI_FLAG should be the cc flag that specifies the ABI.  On most
+# platforms this will be the empty string.  Possible values:
+# +DD64 for 64-bit executable on HP/UX.
+# -n32, -n64, -o32 for SGI/MIPS ABIs.
+

+# To build the parallel collector on Linux, add to the above:
+# -DGC_LINUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC
+# To build the parallel collector in a static library on HP/UX,
+# add to the above:
+# -DGC_HPUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC -D_POSIX_C_SOURCE=199506L
+# To build the thread-safe collector on Tru64, add to the above:
+# -pthread -DGC_OSF1_THREADS
+
+# HOSTCC and HOSTCFLAGS are used to build executables that will be run as
+# part of the build process, i.e. on the build machine.  These will usually
+# be the same as CC and CFLAGS, except in a cross-compilation environment.
+# Note that HOSTCFLAGS should include any -D flags that affect thread support.
+HOSTCC=$(CC)
+HOSTCFLAGS=$(CFLAGS)
+
+# For dynamic library builds, it may be necessary to add flags to generate
+# PIC code, e.g. -fPIC on Linux.
+
+# Setjmp_test may yield overly optimistic results when compiled
+# without optimization.
+
+# These define arguments influence the collector configuration:
+# -DSILENT disables statistics printing, and improves performance.
+# -DFIND_LEAK causes GC_find_leak to be initially set.
+#   This causes the collector to assume that all inaccessible
+#   objects should have been explicitly deallocated, and reports exceptions.
+#   Finalization and the test program are not usable in this mode.
+# -DGC_SOLARIS_THREADS enables support for Solaris (thr_) threads.
+#   (Clients should also define GC_SOLARIS_THREADS and then include
+#   gc.h before performing thr_ or dl* or GC_ operations.)
+#   Must also define -D_REENTRANT.
+# -DGC_SOLARIS_PTHREADS enables support for Solaris pthreads.
+#   (Internally this define GC_SOLARIS_THREADS as well.)
+# -DGC_IRIX_THREADS enables support for Irix pthreads.  See README.irix.
+# -DGC_HPUX_THREADS enables support for HP/UX 11 pthreads.
+#   Also requires -D_REENTRANT or -D_POSIX_C_SOURCE=199506L. See README.hp.
+# -DGC_LINUX_THREADS enables support for Xavier Leroy's Linux threads.
+#   see README.linux.  -D_REENTRANT may also be required.
+# -DGC_OSF1_THREADS enables support for Tru64 pthreads.  Untested.
+# -DGC_FREEBSD_THREADS enables support for FreeBSD pthreads.  Untested.
+#   Appeared to run into some underlying thread problems.
+# -DGC_DARWIN_THREADS enables support for Mac OS X pthreads.  Untested.
+# -DGC_DGUX386_THREADS enables support for DB/UX on I386 threads.
+#   See README.DGUX386.
+# -DGC_WIN32_THREADS enables support for win32 threads.  That makes sense
+#   for this Makefile only under Cygwin.
+# -DGC_THREADS should set the appropriate one of the above macros.
+#   It assumes pthreads for Solaris.
+# -DALL_INTERIOR_POINTERS allows all pointers to the interior
+#   of objects to be recognized.  (See gc_priv.h for consequences.)
+#   Alternatively, GC_all_interior_pointers can be set at process
+#   initialization time.
+# -DSMALL_CONFIG tries to tune the collector for small heap sizes,
+#   usually causing it to use less space in such situations.
+#   Incremental collection no longer works in this case.
+# -DLARGE_CONFIG tunes the collector for unusually large heaps.
+#   Necessary for heaps larger than about 500 MB on most machines.
+#   Recommended for heaps larger than about 64 MB.
+# -DDONT_ADD_BYTE_AT_END is meaningful only with -DALL_INTERIOR_POINTERS or
+#   GC_all_interior_pointers = 1.  Normally -DALL_INTERIOR_POINTERS
+#   causes all objects to be padded so that pointers just past the end of
+#   an object can be recognized.  This can be expensive.  (The padding
+#   is normally more than one byte due to alignment constraints.)
+#   -DDONT_ADD_BYTE_AT_END disables the padding.
+# -DNO_SIGNALS does not disable signals during critical parts of
+#   the GC process.  This is no less correct than many malloc 
+#   implementations, and it sometimes has a significant performance
+#   impact.  However, it is dangerous for many not-quite-ANSI C
+#   programs that call things like printf in asynchronous signal handlers.
+#   This is on by default.  Turning it off has not been extensively tested with
+#   compilers that reorder stores.  It should have been.
+# -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not
+#   have execute permission, i.e. it may be impossible to execute
+#   code from the heap.  Currently this only affects the incremental
+#   collector on UNIX machines.  It may greatly improve its performance,
+#   since this may avoid some expensive cache synchronization.
+# -DGC_NO_OPERATOR_NEW_ARRAY declares that the C++ compiler does not support
+#   the  new syntax "operator new[]" for allocating and deleting arrays.
+#   See gc_cpp.h for details.  No effect on the C part of the collector.
+#   This is defined implicitly in a few environments.  Must also be defined
+#   by clients that use gc_cpp.h.
+# -DREDIRECT_MALLOC=X causes malloc to be defined as alias for X.
+#   Unless the following macros are defined, realloc is also redirected
+#   to GC_realloc, and free is redirected to GC_free.
+#   Calloc and strdup are redefined in terms of the new malloc.  X should
+#   be either GC_malloc or GC_malloc_uncollectable, or
+#   GC_debug_malloc_replacement.  (The latter invokes GC_debug_malloc
+#   with dummy source location information, but still results in
+#   properly remembered call stacks on Linux/X86 and Solaris/SPARC.
+#   It requires that the following two macros also be used.)
+#   The former is occasionally useful for working around leaks in code
+#   you don't want to (or can't) look at.  It may not work for
+#   existing code, but it often does.  Neither works on all platforms,
+#   since some ports use malloc or calloc to obtain system memory.
+#   (Probably works for UNIX, and win32.)  If you build with DBG_HDRS_ALL,
+#   you should only use GC_debug_malloc_replacement as a malloc
+#   replacement.
+# -DREDIRECT_REALLOC=X causes GC_realloc to be redirected to X.
+#   The canonical use is -DREDIRECT_REALLOC=GC_debug_realloc_replacement,
+#   together with -DREDIRECT_MALLOC=GC_debug_malloc_replacement to
+#   generate leak reports with call stacks for both malloc and realloc.
+#   This also requires the following:
+# -DREDIRECT_FREE=X causes free to be redirected to X.  The
+#   canonical use is -DREDIRECT_FREE=GC_debug_free.
+# -DIGNORE_FREE turns calls to free into a noop.  Only useful with
+#   -DREDIRECT_MALLOC.
+# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
+#   Reduces code size slightly at the expense of debuggability.
+# -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of
+#   order by specifying a nonstandard finalization mark procedure  (see
+#   finalize.c).  Objects reachable from finalizable objects will be marked
+#   in a sepearte postpass, and hence their memory won't be reclaimed.
+#   Not recommended unless you are implementing a language that specifies
+#   these semantics.  Since 5.0, determines only only the initial value
+#   of GC_java_finalization variable.
+# -DFINALIZE_ON_DEMAND causes finalizers to be run only in response
+#   to explicit GC_invoke_finalizers() calls.
+#   In 5.0 this became runtime adjustable, and this only determines the
+#   initial value of GC_finalize_on_demand.
+# -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable.
+#   This is useful if either the vendor malloc implementation is poor,
+#   or if REDIRECT_MALLOC is used.
+# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
+#   sets the heap block size.  Each heap block is devoted to a single size and
+#   kind of object.  For the incremental collector it makes sense to match
+#   the most likely page size.  Otherwise large values result in more
+#   fragmentation, but generally better performance for large heaps.
+# -DUSE_MMAP use MMAP instead of sbrk to get new memory.
+#   Works for Solaris and Irix.
+# -DUSE_MUNMAP causes memory to be returned to the OS under the right
+#   circumstances.  This currently disables VM-based incremental collection.
+#   This is currently experimental, and works only under some Unix,
+#   Linux and Windows versions.
+# -DMMAP_STACKS (for Solaris threads) Use mmap from /dev/zero rather than
+#   GC_scratch_alloc() to get stack memory.
+# -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever
+#   the garbage collector detects a value that looks almost, but not quite,
+#   like a pointer, print both the address containing the value, and the
+#   value of the near-bogus-pointer.  Can be used to identifiy regions of
+#   memory that are likely to contribute misidentified pointers.
+# -DKEEP_BACK_PTRS Add code to save back pointers in debugging headers
+#   for objects allocated with the debugging allocator.  If all objects
+#   through GC_MALLOC with GC_DEBUG defined, this allows the client
+#   to determine how particular or randomly chosen objects are reachable
+#   for debugging/profiling purposes.  The gc_backptr.h interface is
+#   implemented only if this is defined.
+# -DGC_ASSERTIONS Enable some internal GC assertion checking.  Currently
+#   this facility is only used in a few places.  It is intended primarily
+#   for debugging of the garbage collector itself, but could also
+# -DDBG_HDRS_ALL Make sure that all objects have debug headers.  Increases
+#   the reliability (from 99.9999% to 100% mod. bugs) of some of the debugging
+#   code (especially KEEP_BACK_PTRS).  Makes -DSHORT_DBG_HDRS possible.
+#   Assumes that all client allocation is done through debugging
+#   allocators.
+# -DSHORT_DBG_HDRS Assume that all objects have debug headers.  Shorten
+#   the headers to minimize object size, at the expense of checking for
+#   writes past the end of an object.  This is intended for environments
+#   in which most client code is written in a "safe" language, such as
+#   Scheme or Java.  Assumes that all client allocation is done using
+#   the GC_debug_ functions, or through the macros that expand to these,
+#   or by redirecting malloc to GC_debug_malloc_replacement.
+#   (Also eliminates the field for the requested object size.)
+#   occasionally be useful for debugging of client code.  Slows down the
+#   collector somewhat, but not drastically.
+# -DSAVE_CALL_COUNT=<n> Set the number of call frames saved with objects
+#   allocated through the debugging interface.  Affects the amount of
+#   information generated in leak reports.  Only matters on platforms
+#   on which we can quickly generate call stacks, currently Linux/(X86 & SPARC)
+#   and Solaris/SPARC and platforms that provide execinfo.h.
+#   Default is zero.  On X86, client
+#   code should NOT be compiled with -fomit-frame-pointer.
+# -DSAVE_CALL_NARGS=<n> Set the number of functions arguments to be
+#   saved with each call frame.  Default is zero.  Ignored if we
+#   don't know how to retrieve arguments on the platform.
+# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
+#   altered stubborn objects, at substantial performance cost.
+#   Use only for debugging of the incremental collector.
+# -DGC_GCJ_SUPPORT includes support for gcj (and possibly other systems
+#   that include a pointer to a type descriptor in each allocated object).
+#   Building this way requires an ANSI C compiler.
+# -DUSE_I686_PREFETCH causes the collector to issue Pentium III style
+#   prefetch instructions.  No effect except on X86 Linux platforms.
+#   Assumes a very recent gcc-compatible compiler and assembler.
+#   (Gas prefetcht0 support was added around May 1999.)
+#   Empirically the code appears to still run correctly on Pentium II
+#   processors, though with no performance benefit.  May not run on other
+#   X86 processors?  In some cases this improves performance by
+#   15% or so.
+# -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style
+#   prefetch instructions.  Same restrictions as USE_I686_PREFETCH.
+#   Minimally tested.  Didn't appear to be an obvious win on a K6-2/500.
+# -DUSE_PPC_PREFETCH causes the collector to issue PowerPC style
+#   prefetch instructions.  No effect except on PowerPC OS X platforms.
+#   Performance impact untested.
+# -DGC_USE_LD_WRAP in combination with the old flags listed in README.linux
+#   causes the collector some system and pthread calls in a more transparent
+#   fashion than the usual macro-based approach.  Requires GNU ld, and
+#   currently probably works only with Linux.
+# -DTHREAD_LOCAL_ALLOC defines GC_local_malloc(), GC_local_malloc_atomic()
+#   and GC_local_gcj_malloc().  Needed for gc_gcj.h interface.  These allocate
+#   in a way that usually does not involve acquisition of a global lock.
+#   Currently requires -DGC_LINUX_THREADS, but should be easy to port to
+#   other pthreads environments.  Recommended for multiprocessors.
+# -DUSE_COMPILER_TLS causes thread local allocation to use compiler-supported
+#   "__thread" thread-local variables.  This is the default in HP/UX.  It
+#   may help performance on recent Linux installations.  (It failed for
+#   me on RedHat 8, but appears to work on RedHat 9.)
+# -DPARALLEL_MARK allows the marker to run in multiple threads.  Recommended
+#   for multiprocessors.  Currently requires Linux on X86 or IA64, though
+#   support for other Posix platforms should be fairly easy to add,
+#   if the thread implementation is otherwise supported.
+# -DNO_GETENV prevents the collector from looking at environment variables.
+#   These may otherwise alter its configuration, or turn off GC altogether.
+#   I don't know of a reason to disable this, except possibly if the
+#   resulting process runs as a privileged user?
+# -DUSE_GLOBAL_ALLOC.  Win32 only.  Use GlobalAlloc instead of
+#   VirtualAlloc to allocate the heap.  May be needed to work around
+#   a Windows NT/2000 issue.  Incompatible with USE_MUNMAP.
+#   See README.win32 for details.
+# -DMAKE_BACK_GRAPH. Enable GC_PRINT_BACK_HEIGHT environment variable.
+#   See README.environment for details.  Experimental. Limited platform
+#   support.  Implies DBG_HDRS_ALL.  All allocation should be done using
+#   the debug interface.
+# -DSTUBBORN_ALLOC allows allocation of "hard to change" objects, and thus
+#   makes incremental collection easier.  Was enabled by default until 6.0.
+#   Rarely used, to my knowledge.
+# -DHANDLE_FORK attempts to make GC_malloc() work in a child process fork()ed
+#   from a multithreaded parent.  Currently only supported by pthread_support.c.
+#   (Similar code should work on Solaris or Irix, but it hasn't been tried.)
+# -DTEST_WITH_SYSTEM_MALLOC causes gctest to allocate (and leak) large chunks
+#   of memory with the standard system malloc.  This will cause the root
+#   set and collected heap to grow significantly if malloced memory is
+#   somehow getting traced by the collector.  This has no impact on the
+#   generated library; it only affects the test.
+# -DPOINTER_MASK=0x... causes candidate pointers to be ANDed with the
+#   given mask before being considered.  If either this or the following
+#   macro is defined, it will be assumed that all pointers stored in
+#   the heap need to be processed this way.  Stack and register pointers
+#   will be considered both with and without processing.
+#   These macros are normally needed only to support systems that use
+#   high-order pointer tags. EXPERIMENTAL.
+# -DPOINTER_SHIFT=n causes the collector to left shift candidate pointers
+#   by the indicated amount before trying to interpret them.  Applied
+#   after POINTER_MASK. EXPERIMENTAL.  See also the preceding macro.

+
+# Setjmp_test may yield overly optimistic results when compiled
+# without optimization.
+# -DSILENT disables statistics printing, and improves performance.
+# -DFIND_LEAK causes GC_find_leak to be initially set.
+#   This causes the collector to assume that all inaccessible
+#   objects should have been explicitly deallocated, and reports exceptions.
+#   Finalization and the test program are not usable in this mode.
+# -DALL_INTERIOR_POINTERS allows all pointers to the interior
+#   of objects to be recognized.  (See gc_priv.h for consequences.)
+# -DSMALL_CONFIG tries to tune the collector for small heap sizes,
+#   usually causing it to use less space in such situations.
+#   Incremental collection no longer works in this case.
+# -DLARGE_CONFIG tunes the collector for unusually large heaps.
+#   Necessary for heaps larger than about 500 MB on most machines.
+#   Recommended for heaps larger than about 64 MB.
+# -DDONT_ADD_BYTE_AT_END is meaningful only with
+#   -DALL_INTERIOR_POINTERS.  Normally -DALL_INTERIOR_POINTERS
+#   causes all objects to be padded so that pointers just past the end of
+#   an object can be recognized.  This can be expensive.  (The padding
+#   is normally more than one byte due to alignment constraints.)
+#   -DDONT_ADD_BYTE_AT_END disables the padding.
+# -DNO_SIGNALS does not disable signals during critical parts of
+#   the GC process.  This is no less correct than many malloc 
+#   implementations, and it sometimes has a significant performance
+#   impact.  However, it is dangerous for many not-quite-ANSI C
+#   programs that call things like printf in asynchronous signal handlers.
+#   This is on by default.  Turning it off has not been extensively tested with
+#   compilers that reorder stores.  It should have been.
+# -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not
+#   have execute permission, i.e. it may be impossible to execute
+#   code from the heap.  Currently this only affects the incremental
+#   collector on UNIX machines.  It may greatly improve its performance,
+#   since this may avoid some expensive cache synchronization.
+# -DGC_NO_OPERATOR_NEW_ARRAY declares that the C++ compiler does not support
+#   the  new syntax "operator new[]" for allocating and deleting arrays.
+#   See gc_cpp.h for details.  No effect on the C part of the collector.
+#   This is defined implicitly in a few environments.  Must also be defined
+#   by clients that use gc_cpp.h.
+# -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be defined
+#   as aliases for X, GC_realloc, and GC_free, respectively.
+#   Calloc is redefined in terms of the new malloc.  X should
+#   be either GC_malloc or GC_malloc_uncollectable.
+#   The former is occasionally useful for working around leaks in code
+#   you don't want to (or can't) look at.  It may not work for
+#   existing code, but it often does.  Neither works on all platforms,
+#   since some ports use malloc or calloc to obtain system memory.
+#   (Probably works for UNIX, and win32.)
+# -DIGNORE_FREE turns calls to free into a noop.  Only useful with
+#   -DREDIRECT_MALLOC.
+# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
+#   Reduces code size slightly at the expense of debuggability.
+# -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of
+#   order by specifying a nonstandard finalization mark procedure  (see
+#   finalize.c).  Objects reachable from finalizable objects will be marked
+#   in a sepearte postpass, and hence their memory won't be reclaimed.
+#   Not recommended unless you are implementing a language that specifies
+#   these semantics.  Since 5.0, determines only only the initial value
+#   of GC_java_finalization variable.
+# -DFINALIZE_ON_DEMAND causes finalizers to be run only in response
+#   to explicit GC_invoke_finalizers() calls.
+#   In 5.0 this became runtime adjustable, and this only determines the
+#   initial value of GC_finalize_on_demand.
+# -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable.
+#   This is useful if either the vendor malloc implementation is poor,
+#   or if REDIRECT_MALLOC is used.
+# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
+#   sets the heap block size.  Each heap block is devoted to a single size and
+#   kind of object.  For the incremental collector it makes sense to match
+#   the most likely page size.  Otherwise large values result in more
+#   fragmentation, but generally better performance for large heaps.
+# -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever
+#   the garbage collector detects a value that looks almost, but not quite,
+#   like a pointer, print both the address containing the value, and the
+#   value of the near-bogus-pointer.  Can be used to identifiy regions of
+#   memory that are likely to contribute misidentified pointers.
+# -DKEEP_BACK_PTRS Add code to save back pointers in debugging headers
+#   for objects allocated with the debugging allocator.  If all objects
+#   through GC_MALLOC with GC_DEBUG defined, this allows the client
+#   to determine how particular or randomly chosen objects are reachable
+#   for debugging/profiling purposes.  The gc_backptr.h interface is
+#   implemented only if this is defined.
+# -DGC_ASSERTIONS Enable some internal GC assertion checking.  Currently
+#   this facility is only used in a few places.  It is intended primarily
+#   for debugging of the garbage collector itself, but could also
+# -DDBG_HDRS_ALL Make sure that all objects have debug headers.  Increases
+#   the reliability (from 99.9999% to 100%) of some of the debugging
+#   code (especially KEEP_BACK_PTRS).  Makes -DSHORT_DBG_HDRS possible.
+#   Assumes that all client allocation is done through debugging
+#   allocators.
+# -DSHORT_DBG_HDRS Assume that all objects have debug headers.  Shorten
+#   the headers to minimize object size, at the expense of checking for
+#   writes past the end of an object.  This is intended for environments
+#   in which most client code is written in a "safe" language, such as
+#   Scheme or Java.  Assumes that all client allocation is done using
+#   the GC_debug_ functions (or through the macros that expand to these.
+#   (Also eliminates the field for the requested object size.)
+#   occasionally be useful for debugging of client code.  Slows down the
+#   collector somewhat, but not drastically.
+# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
+#   altered stubborn objects, at substantial performance cost.
+#   Use only for debugging of the incremental collector.
+# -DGC_GCJ_SUPPORT includes support for gcj (and possibly other systems
+#   that include a pointer to a type descriptor in each allocated object).
+#   Building this way requires an ANSI C compiler.
+# -DUSE_I686_PREFETCH causes the collector to issue Pentium III style
+#   prefetch instructions.  No effect except on X86 Linux platforms.
+#   Assumes a very recent gcc-compatible compiler and assembler.
+#   (Gas prefetcht0 support was added around May 1999.)
+#   Empirically the code appears to still run correctly on Pentium II
+#   processors, though with no performance benefit.  May not run on other
+#   X86 processors?  In some cases this improves performance by
+#   15% or so.
+# -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style
+#   prefetch instructions.  Same restrictions as USE_I686_PREFETCH.
+#   UNTESTED!!
+# -DGC_USE_LD_WRAP in combination with the gld flags listed in README.linux
+#   causes the collector some system and pthread calls in a more transparent
+#   fashion than the usual macro-based approach.  Requires GNU ld, and
+#   currently probably works only with Linux.

+
+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.
