- Subject: Patch: libstdc++-v3 irix6.2 fix for 70 broken g++ testsuite results
This patch corrects a problem when running the g++ testsuite on
irix6.2. I'd very much like the comments I inserted in the patch to
stand on their own so I purposely left out any explanation here. If
there not clear below, let me know and I'll gladly revise them.
This patch corrects the roughly 70 failure difference in the g++
results between here:
http://gcc.gnu.org/ml/gcc-testresults/2002-04/msg00090.html
and here:
http://gcc.gnu.org/ml/gcc-testresults/2002-04/msg00149.html
and I've been using it ever since.
Tested on mips-sgi-irix6.2. Ok to install on the trunk?
(I'll privately queue it up for 3.1.1.)
Thanks,
