I don't have the documentation here right now, but I believe that the
AT&T Sys V PCC2 cross compiler for the 68000 can be built with 16 or 32
bit ints, depending on how you like it.

The question of 16 and 32 bit ints is addressed in Consulair C
with a compil time switch.  The manual states that 16 bit ints
is implied by the architecture of the 68000.  Use of the 16 bit ints
will generate smaller, faster code, but more care must be taken to insure
that word boundaries are respected.
