+# 1) Need to explicitly set LTCXXCOMPILE so that AM_CXXFLAGS is
+# last. (That way, things like -O2 passed down from the toplevel can
+# be overridden by --enable-debug.)
+
+# 2) In general, libtool expects an argument such as `--tag=CXX' when
+# using the C++ compiler, because that will enable the settings
+# detected when C++ support was being configured.  However, when no
+# such flag is given in the command line, libtool attempts to figure
+# it out by matching the compiler name in each configuration section
+# against a prefix of the command line.  The problem is that, if the
+# compiler name and its initial flags stored in the libtool
+# configuration file don't match those in the command line, libtool
+# can't decide which configuration to use, and it gives up.  The
+# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
+# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
+# attempt to infer which configuration to use.
+#
+# We have to put --tag disable-shared after --tag CXX lest things

+# 3) We'd have a problem when building the shared libstdc++ object if
+# the rules automake generates would be used.  We cannot allow g++ to
+# be used since this would add -lstdc++ to the link line which of
+# course is problematic at this point.  So, we get the top-level

+# compilation driver.

+# can't decide which configuration to use, and it gives up.  The

+   *
+   *  @param __mangled_name A NUL-terminated character string
+   *  containing the name to be demangled.
+   *
+   *  @param __output_buffer A region of memory, allocated with
+   *  malloc, of @a *__length bytes, into which the demangled name is
+   *  stored.  If @a __output_buffer is not long enough, it is
+   *  expanded using realloc.  @a __output_buffer may instead be NULL;
+   *  in that case, the demangled name is placed in a region of memory
+   *  allocated with malloc.
+   *
+   *  @param __length If @a __length is non-NULL, the length of the
+   *  buffer containing the demangled name is placed in @a *__length.
+   *
+   *  @param __status @a *__status is set to one of the following values:
+   *   0: The demangling operation succeeded.
+   *  -1: A memory allocation failiure occurred.
+   *  -2: @a mangled_name is not a valid name under the C++ ABI mangling rules.
+   *  -3: One of the arguments is invalid.
+   *
+   *  @return A pointer to the start of the NUL-terminated demangled
+   *  name, or NULL if the demangling fails.  The caller is
+   *  responsible for deallocating this memory using @c free.
+   *
+   *  The demangling is performed using the C++ ABI mangling rules,
+   *  with GNU extensions. For example, this function is used in
+   *  __gnu_cxx::__verbose_terminate_handler.
+   * 
+   *  See http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt12ch39.html
+   *  for other examples of use.
+   *
+   *  @note The same demangling functionality is available via
+   *  libiberty (@c <libiberty/demangle.h> and @c libiberty.a) in GCC
+   *  3.1 and later, but that requires explicit installation (@c
+   *  --enable-install-libiberty) and uses a different API, although
+   *  the ABI is unchanged.

+ *
+ *  A brief overview of an ABI is given in the libstdc++ FAQ, question
+ *  5.8 (you may have a copy of the FAQ locally, or you can view the online
+ *  version at http://gcc.gnu.org/onlinedocs/libstdc++/faq/index.html#5_8).
+ *
+ *  GCC subscribes to a cross-vendor ABI for C++, sometimes
+ *  called the IA64 ABI because it happens to be the native ABI for that
+ *  platform.  It is summarized at http://www.codesourcery.com/cxx-abi/
+ *  along with the current specification.
+ *
+ *  For users of GCC greater than or equal to 3.x, entry points are
+ *  available in <cxxabi.h>, which notes, <em>"It is not normally
+ *  necessary for user programs to include this header, or use the
+ *  entry points directly.  However, this header is available should
+ *  that be needed."</em>

+// The old code supported scenarios 1-3 but was broken since it used a global

+// initlization of a guarded static variable. The following created a dead-lock
+// with the old code.
+//
+//	Thread 1 acquires the global mutex.
+//	Thread 1 starts initializing static variable.
+//	Thread 1 creates thread 2 during initialization.
+//	Thread 2 attempts to acuqire mutex to initialize another variable.
+//	Thread 2 blocks since thread 1 is locking the mutex.
+//	Thread 1 waits for result from thread 2 and also blocks. A deadlock.
+//
+// The new code here can handle this situation and thus is more robust. Howere,
+// we need to use the POSIX thread conditional variable, which is not supported
+// in all platforms, notably older versions of Microsoft Windows. The gthr*.h
