Why not do something along the lines of:
#define Meta_Assert(expr) typedef int __META_ASSERT__[(expr)? 1 : -1];

and then simply asserting it runtime? Like:
  Meta_Assert( sizeof(int) = sizeof(void*) );
Of course if you DO want it to work with different sizes, a different
approach is wanted. But mostly thses kind of things are nice, as they check
at compile time that certain truths about the runtime are true.
