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.
