   Of course! In particular GNAT requires that all code compile warning free
   (both the C and Ada parts). But that's not a reason for having *portable*
   ways of removing warnings for non-portable code!

In other areas, GCC already has portable ways of removing warnings
for non-portable code.

Should:
	char * x;
	short * y;
	[...]
	y = (short *)x;

always generate a warning?
