BTW this is typical.  The only 64-bit platforms using a 64-bit "int"
are unusual ones, such as supercomputers and DSP chips (which might
even use a 64-bit "char").  Most Unix-derived systems, including Linux
and MacOS, use a 32-bit int and 64-bit long on 64-bit hardware.  Some
of the reasons for this are given here (search for "1995"):

64-bit Windows takes this a step further: even "long" stays at 32
bits.  This is done primarily to to make it easier to use existing
code and data:
