I can find no agreement was to what counts as a short, long, int, at all.
If it matters, use the length specific variable names.

Server/desktop platforms usually have int=32 bits; long is a bit more
variable. It’d probably be 16 bits on a Z80 or similar where memory and
computation are in short supply.

 To clarify: int would probably be 16 bits on a Z80. long still has to be
at least 32 bits.
 

Yes.
It was a pain because the natural manipulation on an 8 bit chip is 8 bits.
making it 16 bit led to a lot of extra code.
