This sounds like a known issue compiling pre-2004 glibc with newer gcc's, rather than a bug.
See
http://kegel.com/crosstool/crosstool-0.28-rc37/patches/glibc-2.3.2/glibc-2.3.2-allow-gcc-3.4-nounit.patch
http://kegel.com/crosstool/crosstool-0.28-rc37/patches/glibc-linuxthreads-2.3.2/glibc-linuxthreads-2.3.2-allow-3.4.patch
for how to deal with it in glibc-2.3.2 / linuxthreads
(actually, those patches were backported from glibc just about the time
glibc-2.3.3 was tagged; see the comments at the top of the patches).
