            Bug ID: 65999
           Summary: c11 compliance - fopen_s not supported
           Product: gcc
           Version: 5.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: darlingm at gmail dot com
  Target Milestone: ---

Microsoft implemented fopen_s some time ago.  According to
http://en.cppreference.com/w/c/io/fopen, it was made part of the C11 standard. 
(Forgive me if they're wrong.)

GCC v5.1.0 doesn't seem to support it.  grep fopen_s -r * through its source
finds nothing.  grep'ing through /usr/include (gcc 4.9.2) and
/usr/local/include (gcc 5.1.0) only finds it in
/usr/include/wine/msvcrt/{stdio.h & wchar.h}
