gcc bug impacts glibc cvs

[Jack Howarth]

   I haven't seen any feedback from Ulrich concerning this
cross-platform gcc bug that prevents undefined weak symbols
from working properly. The discussion so far on the gcc-bugs
mailing list includes...

http://gcc.gnu.org/ml/gcc-bugs/2001-03/msg00383.html

This is in response to Franz Sirl's proposed patches
to fix the problems glibc cvs has on linuxppc (and
perhaps other platforms).

If, as Geoff observes, undefined weak symbol usage is broken
in gcc 2.95.3 and 3.0, shouldn't we avoid it for now?

ps I did try Franz's suggested patch from...
http://sources.redhat.com/ml/libc-alpha/2001-03/msg00020.html
...and glibc cvs complies fine and passes all of make check
with that suggested hack.
