When trying to reinstall glibc (due to changed USE flags), it successfully compile the x86 ABI part and then fails during the configuration of the amd64 ABI part with the above error. Reproducible: Always Steps to Reproduce: 1. emerge -av glibc 2. 3.

sorry for double posting the comment. It didn't show up on the attachments details page, so I thought bugzilla didn't get it at the first time. Anyway I was not able to upload the build logfile due to size restrictions in bugzilla (file is ~12M, but only 2M are allowed).

it fails because you use -Wextra. glibc needs to test with -Werror because unknown attributes simply get warned about and thus there is no way to compile test for it w/out using -Werror.
