Check in a pristine copy of GCC 4.8.1.

The copy of GCC that we use for Android is still not working for
mingw. Rather than finding all the differences that have crept into
our GCC, just check in a copy from
ftp://ftp.gnu.org/gnu/gcc/gcc-4.9.3/gcc-4.8.1.tar.bz2.

GCC 4.8.1 was chosen because it is what we have been using for mingw
thus far, and the emulator doesn't yet work when upgrading to 4.9.

+
+2001-04-04  Hans Boehm  <hans_boehm@hp.com>
+
+	* finalize.c:
+	- Accomodate finalization requests for static objects.
+	  (Will be required by hash synchronization.  May be needed
+	  in some configurations now.)
+
+	* gc_priv.h:
+	- Define MIN_WORDS.  All allocation requests are rounded
+	  up to at least this size.  Removes a subtle assumption that
+	  Java objects have a 2 word header.
+
+	* gcconfig.h:
+	- Adjust Linux/IA64 configuration for non-ancient kernels.
+	  (Necessary fix for IA64.)
+
+	* linux_threads.c:

+	  for Linux/PA-RISC.
+
+	* malloc.c:

+
+	* misc.c:
+	- Handle MIN_WORDS.
+	- Change stack cleaning code to typically clear about one tenth
+	  the memory it used to in the threads configuration.  Occasionally
+	  still clear more.  (This is really a fix for a long-standing
+	  and fairly significant performance bug with threads.)
+
+	* os_dep.c:
+	- Fix the code for finding the beginning of the data segment under
+	  Linux.  I believe this is necessary for some IA64 Linux
+	  distributions.  It will also helo other platforms, though those
+	  may additionally require a gcconfig.h adjustment.  (This basically
+	  works around the absence of a data_start or __data_start
+	  definition in glibc.)
+
+	* test.c:
+	- Handle rounding due to MIN_WORDS.
