Bug #: 13566
Summary: Glibc should define gets for C++11
Product: glibc
Version: 2.15
Status: NEW
Severity: normal
Priority: P2
Component: libc
AssignedTo: drepper.fsp@gmail.com
ReportedBy: vries@gcc.gnu.org
Classification: Unclassified
With this change:
...
[BZ #13528]
* libio/stdio.h: Do not declare gets for ISO C11 and _GNU_SOURCE.
...
gets is no longer defined for C++11, while it should be. This causes breakage
when building libstdc++. See also discussion at
http://gcc.gnu.org/ml/gcc/2012-01/msg00041.html .

That build failure is in C++03 code, not C++11
gets() needs to be defined for C++ even when _GNU_SOURCE is defined.
I suggest checking whether __cplusplus <= 201103L

...And un-fixed in this commit, a day later:
http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=c3a87236702cb73be1dada3438bbd3c3934e83f8
Looks like either that needs to be rolled back, or gcc needs to be changed to
not define _GNU_SOURCE. (But I bet that latter change will break lots more
stuff in libstdc++...)

Ah, indeed.
Well, I'll let the gcc and glibc people figure out what to do here. Nothing
has been released with these changes yet (at least not AFAIK), so it's only
hitting people trying to use head versions, which isn't many.

GCC was fixed for 4.7. glibc patch for GCC <= 4.6 pending review:

Fixed, again, by removing the __USE_GNU conditional after further discussion on
libc-alpha.
