We were all quite concerned about it until somebody reported a workaround; see
http://www.winehq.com/hypermail/wine-devel/2003/02/0260.html
The workaround is to give the command
   export LD_ASSUME_KERNEL=2.2.5
before running Wine (and probably before running configure, too).
(This is documented in each distro's beta release notes, e.g.
http://distro.ibiblio.org/pub/Linux/distributions/redhat/beta/phoebe/en/os/i386/RELEASE-NOTES.html )
Have you tried this yet?
What CPU and OS are you using?

That patch was bogus, it is not the right fix.  The right fix is
for Wine to adapt to the new threading model in glibc2.3 (not 3.2, I think),
which is far superior to the old one.  See http://www.kegel.com/c10k.html#threads.nptl

The changes needed are deep.  Alexandre has started on them, but
given the workaround, it can probably wait a bit.
