cast: make sure suncc sees a constant.

2012-03-29T06:18:57+00:00

cast_const() et. al. are supposed to be a constant expression, so you can do things like:
	static char *p = cast_const(char *, (const char *)"hello");

Unfortunately, a cast to intptr_t and arithmetic makes suncc reject it as
a constant expression.  We need the cast, because (1) the expression could be
a void *, so we can't just add to it, and (2) gcc complains with -Wcast-qual
without it.

So instead of adding BUILD_BUG_OR_ZERO, we use a ? :, which keeps everyone happy.

cast: test/compile_fail-cast_static.c should fail without COMPOUND_LITERALS.

It still gave a warning on gcc, because casting a char to a char* gives a warning.  Not so on sun CC.
