I just finished the glibc upgrade from 2.3.4 to 2.5-r4 (which required an upgrade from gcc 3.3.5 to 4.1.2 as a pre-requisite), and the testsuite now succeeds.

I would recommend a ./configure test for glibc2.3.4 and/or gcc 3.3.5 as an unsupported configuration, or at least a caveat in the build docs.

Thanks for all your help Alex and Tobi!
