static_assert in G++

[Reuben Thomas]

I noticed this in lib/verify.h:

/* The condition (99 < __GNUC__) is temporary, until we know about the
   first G++ release that supports static_assert.  */
#if (99 < __GNUC__) && defined __cplusplus
# define _GL_HAVE_STATIC_ASSERT 1
#endif

The relevant commit is:

commit ef1271787
Author: Bruno Haible <address@hidden>
Date:   Sat Apr 9 02:12:11 2011 +0200

    verify: Fix syntax error with GCC 4.6 in C++ mode.
 

This is odd, since the GCC web page on C++11 support: https://gcc.gnu.org/projects/cxx-status.html#cxx11

says that static assertions have been supported for C++ since GCC 4.3:

Static assertions

N1720

GCC 4.3

__cpp_static_assert >= 200410

Assuming I'm failing to understand something, could the comment in verify.h be clarified as to what exactly is missing, if indeed it still is?
