Stefan Liebler e1fd4bbe31 Fix namespace violation in stdio.h and sys/stat.h if build with optimization. [BZ #26376] ... If build with optimization, stdio.h and sys/stat.h are defining some inlining functions. This leads to test fails if glibc is build with the following commands. (Note that the conformtests usually builds without optimization or other CFLAGS): <glibc>/configure CC="gcc -O3" --prefix=/usr make make subdirs=conform check - FAIL: conform/XPG4/stdio.h/conform - FAIL: conform/XPG42/stdio.h/conform out-files: ... PASSCOMBINED: Availability of variable optopt PASSCOMBINED: Type of variable optopt Namespace violation: "getc_unlocked" Namespace violation: "getchar_unlocked" Namespace violation: "putc_unlocked" Namespace violation: "putchar_unlocked" FAIL: Namespace of <stdio.h> ---------------------------------------------------------------------------- Total number of tests : 168 Number of failed tests : 1 Number of xfailed tests : 0 Number of skipped tests : 0 - FAIL: conform/POSIX2008/sys/stat.h/conform out-file: ... PASSCOMBINED: Availability of function utimensat PASSCOMBINED: Type of function utimensat Namespace violation: "mknodat" FAIL: Namespace of <sys/stat.h> ---------------------------------------------------------------------------- Total number of tests : 97 Number of failed tests : 1 Number of xfailed tests : 0 Number of skipped tests : 0 For getc_unlocked, getchar_unlocked, putc_unlocked, putchar_unlocked in stdio.h, those are defined "# ifdef __USE_POSIX" instead of "#ifdef __USE_POSIX199506" for the non-inlining declaration. See also "Bug 20014 - stdio.h namespace for pre-threads POSIX" (https://sourceware.org/bugzilla/show_bug.cgi?id=20014). For mknodat in sys/stat.h, those are defined "# ifdef __USE_ATFILE" instead of the additional guard "# if defined __USE_MISC || defined __USE_XOPEN_EXTENDED".		2020-08-20 10:45:26 +02:00
