Fix perror fileno namespace (bug 17633).
perror, an ISO C function, uses fileno, which is not an ISO C function. This patch makes it use __fileno instead. (The nearby call to fdopen is not a problem because that's #defined to _IO_new_fdopen.) Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by this patch). [BZ #17633] * stdio-common/perror.c (perror): Call __fileno instead of fileno. * conform/Makefile (test-xfail-ISO/stdio.h/linknamespace): Remove variable. (test-xfail-ISO99/stdio.h/linknamespace): Likewise. (test-xfail-ISO11/stdio.h/linknamespace): Likewise.
