I just thought I would clarify Consulair Mac-C's place in this discussion and
mention that I do know that Megamax sizeof(int) is 2.
PDP-11 VAX IBM-370 Mac-C(default) Mac-C(option)
sizeof(short) 2 2 2 2 1
sizeof(int) 2 4 4 4 2
sizeof(long) 4 4 4 4 4
Bill Duvall( Consulair ) states in the manual that the default of 16 bit
shorts and 32 bit longs is for portability and that the option of 8 bit shorts
and 16 bit int's is optimum for the architecture of the 68000 and generates
faster, more compact code.
