Subject: [PATCH] stdio: don't assume gets any more
|
| 9 |
|
| 10 |
Gnulib intentionally does not have a gets module, and now that C11
|
| 11 |
and glibc have dropped it, we should be more proactive about warning
|
| 12 |
any user on a platform that still has a declaration of this dangerous
|
| 13 |
interface.
