Fix stdio.h cuserid namespace (bug 19989).
stdio.h declares cuserid if __USE_XOPEN. But this was removed in the 2001 edition of POSIX. The #endif comment "Use X/Open, but not issue 6." reflects the correct logic, but does not correspond to the #ifdef. The use of a correct libc-hacker. The online archives for libc-hacker in August 2000 are broken, but the messages can be found in the qmail archives in /sourceware1/qmail/lists-sourceware/libc-hacker/archive/26 if you have shell access to sourceware. The issue showed up in August 2000 because of a warning about a non-prototype definition in sysdeps/posix/cuserid.c when there was no previous prototype declaration. Since we've now eliminated non-prototype function definitions, that issue does not apply. The other points from that discussion were about whether it should be included in _GNU_SOURCE; whether _GNU_SOURCE should include "everything"; whether deprecated interfaces such as this should be excluded from it; and whether, even given exclusion of deprecated interfaces, it should apply for deprecations in a version of POSIX that at that time had not been released. This patch follows the more conservative approach to a fix of keeping the interface in _GNU_SOURCE. That matches how L_cuserid is handled. I think there is a strong case for eliminating this interface from _GNU_SOURCE (but this may not automatically be the case for every interface removed in newer POSIX versions), but then L_cuserid should also be removed from _GNU_SOURCE (in stdio-common/stdio_lim.h.in) at the same time. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). [BZ #19989] * libio/stdio.h (cuserid): Do not declare if [__USE_XOPEN2K && !__USE_GNU]. * conform/Makefile (test-xfail-XOPEN2K8/stdio.h/conform): Remove variable.
