Work around glibc bug#15589, where freopen mishandles the case where stdin etc. are already closed. * doc/posix-functions/freopen.texi (freopen): Document the bug. * lib/freopen.c (_GL_ALREADY_INCLUDING_STDIO_H): Define this instead of __need_FILE, as the latter does not work with glibc. Include <fcntl.h>, for open flags. (rpl_freopen): Work around glibc bug. * m4/freopen.m4 (gl_FUNC_FREOPEN): Check for bug. * modules/freopen (Depends-on): Add fcntl-h. * tests/test-freopen.c (main): Test for bug.
