This is gcc 4.7.1 and eglibc 2.13. I upgraded to Debian Wheezy's current
gcc 4.7.2 without any changes. I'm not able to reproduce it locally on a
Debian sid system either. I also tried a clean bootstrap 

http://honk.sigxcpu.org:8001/job/libvirt-build/474/

but the problem persists:

$ nm src/.libs/libvirt_util.a | grep rpl_fwrite
00000760 T rpl_fwrite
00000000 T rpl_fwrite
00000300 T rpl_fwrite

Any information I can provide to diagnose this further?

P.S.: I've removed the mailing list from the build reports temporarily to
not spam the list with new build failures until this is fixed.
