/libc/sysdeps/linux/common/bits/confname.h line 530 has _SC_THREAD_ROBUST_PRIO_PROTECT, when it should be _SC_THREAD_ROBUST_PRIO_PROTECT As a final value in an enum gcc coughs at the comma. Looking at the git tree online this is still present though I tripped over it when using uclibc 0.9.31 as a part of buildroot2010.05.
Fixes as 4e38c284bc8b3bff95543f246f3e0d3ee5a045ab. Thanks!
