+    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.
+    Reported by Christer Solskogen.
