I think we don't need to touch _Static_assert, if the compiler doesn't implement it there's not much we can do.

>[+] Standard C library doesn't define static_assert -> define
>static_assert

IMO that's the only bug here, fixed by -Dstatic_assert=_Static_assert

>B. Building C++ code:
>[+] Compiler doesn't have _Static_assert -> define _Static_assert

Is Apple C++ assert.h buggy too?
