And in include/features.h (from glibc 2.12 e28c887):

#if (_POSIX_C_SOURCE - 0) >= 200112L

what is it you're trying to report ?  the man page already reads:
       mkstemp():
           _XOPEN_SOURCE >= 500
               || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200112L
               || /* Glibc versions <= 2.19: */ _SVID_SOURCE || _BSD_SOURCE

can you attach a patch ?
