stdio: don't assume gets any more Gnulib intentionally does not have a gets module, and now that C11 and glibc have dropped it, we should be more proactive about warning any user on a platform that still has a declaration of this dangerous interface. * m4/stdio_h.m4 (gl_STDIO_H, gl_STDIO_H_DEFAULTS): Drop gets support. * modules/stdio (Makefile.am): Likewise. * lib/stdio-read.c (gets): Likewise. * tests/test-stdio-c++.cc: Likewise. * m4/warn-on-use.m4 (gl_WARN_ON_USE_PREPARE): Fix comment. * lib/stdio.in.h (gets): Make warning occur in more places. * doc/posix-functions/gets.texi (gets): Update documentation.
