memrchr(3): depends on _GNU_SOURCE

memrchr(3): depends on _GNU_SOURCE

[Markus Peuhkuri]

At manual page (memchr, memrchr and rawmemchr) it is listed that only
rawmemchr needs _GNU_SOURCE feature test macro. However, at least in
/usr/include/string.h shipped with Debian Lenny and Ubuntu 9.04 both
have also memrchr in same #ifdef __USE_GNU block.

Thanks for the report. Indeed, it should be at the same line. Fixed for 3.24.

Cheers,
