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.

+This directory contains files from examples of regression hunts, cut
+down to smaller ranges to save space and time.  Try these out before
+using the tools on your own tests.  First, update gcc-svn-env and
+common.config for your own environment.
+
+Each of the examples has multiple files:
+
+  *.list files were created using gcc-svn-patchlist
+
+  *.config files were written by hand based on earlier config files;
+  the commented-out pieces are left as templates in case they're needed
+
+  *.c, *.c++ are source files for the test, usually taken directly from
+  the PR
+
+  *.test files are tests specific to a bug when an existing gcc-test-*
+  script can't be used
+
+  *.log files are output from various scripts
+
+Examples, where the identifier is the PR number:
+
+  28970   wrong-code
+  29106   special test, 4.1 branch
+  29578   bogus-warning
+  29906a  ice-on-valid-code, break
+  29906b  ice-on-valid-code, fix
+  30643   special test, cross compiler
+
+Cut down the range even further by setting LOW_PATCH and HIGH_PATCH
+within the config file to ids where the log file shows the test
+passed or failed.
+
+To run one, do
+
+  reg-hunt 28970.config > 28970.log 2>&1
+
+Check on its progress using
+
+  ./reg-watch 28970.log
+
+To run them all, do
+
+  echo "hunt 28970" > queue
+  echo "hunt 29106" >> queue
+  echo "hunt 29578" >> queue
+  echo "hunt 29906a" >> queue
+  echo "hunt 29906b" >> queue
+  echo "hunt 30643" >> queue
+  ./testall queue
+
+This allows you to add more to the queue if you're setting up lots of
+hunts.
