stat: detect FreeBSD bug Like Solaris 9, FreeBSD 7.2 mistakenly allows stat("link-to-file/"). Unlike Solaris, it correctly forbids stat("file/"). A number of interfaces are affected (such as utimes), but replacing stat is enough to catch several by reusing the Solaris 9 fixes. * m4/stat.m4 (gl_FUNC_STAT): Also detect FreeBSD bug with slash on symlink. * doc/posix-functions/stat.texi (stat): Document the bug. * tests/test-stat.h (test_stat_func): Add argument. * tests/test-stat.c (main): Adjust caller. * tests/test-fstatat.c (main): Likewise. * modules/stat-tests (Depends-on): Add stdbool, symlink.
