   9     stdio: don't assume gets any more
  10
  11     Gnulib intentionally does not have a gets module, and now that C11
  12     and glibc have dropped it, we should be more proactive about warning
  13     any user on a platform that still has a declaration of this dangerous
  14     interface.
  15
  16     * m4/stdio_h.m4 (gl_STDIO_H, gl_STDIO_H_DEFAULTS): Drop gets
  17     support.
  18     * modules/stdio (Makefile.am): Likewise.
  19     * lib/stdio-read.c (gets): Likewise.
  20     * tests/test-stdio-c++.cc: Likewise.
  21     * m4/warn-on-use.m4 (gl_WARN_ON_USE_PREPARE): Fix comment.
  22     * lib/stdio.in.h (gets): Make warning occur in more places.
  23     * doc/posix-functions/gets.texi (gets): Update documentation.
