             Bug #: 51785
           Summary: gets not anymore declared
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: drepper.fsp@gmail.com


glibc 2.15 and later don't declare gets anymore for ISO C11 mode and if
_GNU_SOURCE is defined.  This causes problems with the cstdio header which
unconditionally uses

using ::gets;


Something has to be done about this.  If you want glibc to define a macro to
signal that gets is not declared let me know.  Otherwise recognize __USE_GNU.

The problem still applies to the trunk.
