Here's a sample of the changes necessary to make SPIM (and XSPIM) compile
on the Amiga. You will need gcc 2.3.3 (maybe other versions will work),
a lex derivative and libnet.a to link with. Thus you need ixemul v39.47 too.
To run SPIM you need to assign SPIM: to some spot where SPIM can find the
trap.handler (usually spim:lib/trap.handler). This can be specified in the
makefile (which is supplied at the bottom of this text)
