+ commit 66712c23388e93e5c518ebc8515140fa0c807348

+ 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.

+
+This patch just gets rid of the offending part.
