The above syntax won't work on any compiler I've ever heard of. For
Lattice C, try this:

#define int32	long
#define uns32	<cause syntax error>
#define int16	int
#define uns16	unsigned
#define int8	short
#define uns8	char

If you try to port code to Lattice C that uses an uns32, you will get
a syntax error at the location in the code that needs to be rewritten
so it doesn't require an unsigned long.
