>Description:

        I'm trying to use gcc-3.1 to get a stack aligned libc.  I've
downloaded the release or HEAD versions of libc; in either case, the
build is uneventful, but I get testsuite failures.  If I use
aggressive optimization flags (-O3 -march=i686 -ffast-math
-funroll-loops -fomit-frame-pointer -malign-jumps=3 -malign-loops=3
-malign-functions=3 -mpreferred-stack-boundary=3) I get tons of
failures, but if I used the default and redifine CC as above I only
get the 4 listed below.

             Would you recommend installing this version?

Thanks in advance (Sorry for the CC to bug-glibc, I'd sent this to
address@hidden a few days ago and heard nothing).
