"big" integer constants

I don't know of any where sizeof(short) is less than 16 bits at least.
I picked 65535U because it's a valid "big" number regardless of how
big int/short/long are, as long as they're 16 bits or more.  I don't
think gcc has any support for 8-bit "int" targets anywhere.

At the very least, you know sizeof(int) >= sizeof(short) on all
targets.

Heh.  I'm trying to get a new port finished :-)
