8 years agoUse static_assert for STATIC_ASSERT for C++11 onwards
David Malcolm [Wed, 27 Jul 2016 14:49:06 +0000 (14:49 +0000)]
Use static_assert for STATIC_ASSERT for C++11 onwards

C++11 has a
  static_assert (COND, MESSAGE)
which gives more readable error messages for STATIC_ASSERT than our
current implementation.

This patch makes us use it if __cplusplus >= 201103L

There's also a provisional static_assert (COND) in C++1z, but presumably
we should wait until that one is fully standardized before using it.

made use of _OBSTACK_SIZE_T.  So the configury changes to define
