    Make _Static_assert() work with GCC in older C++ standards.
    GCC only activates C11 keywords in C mode, not C++ mode. This means
    that when targeting an older C++ standard, we cannot fall back to using
    _Static_assert(). In this case, do define _Static_assert() as a macro
    that uses a typedef'ed array.
