+/* Returns the biggest unsigned integer with the sizeof x */ +#define biggest_unsigned_int(x) (~(x)0)
Nope - biggest_unsigned_int(unsigned char) is probably 0xffffffff
To correct myself, it is actually ((int)(-1)) (ie a signed value).
In any event this is just a terrible macro, and too stupid to live.
