[mpich-discuss] MPICH 3.2.1 build error with icc+ifort: undefined reference to `_Static_assert'

[Jeff Hammond]

_Static_assert comes from C11.

src/include/mpir_assert.h does a direct test for C11 support based upon the
GCC version, which is unsafe since ICC (and other non-GCC compilers) define
these macros.

/* GCC 4.6 added support for _Static_assert:
 * http://gcc.gnu.org/gcc-4.6/changes.html */
#if (__GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ >= 6)) && !defined
__cplusplus
#define HAVE_C11__STATIC_ASSERT 1
#endif

MPICH needs to test for _Static_assert properly using configure.  You
should file a GitHub issue to track this.
