One possibility is to use GCC, configured for a FreeBSD host and 68K
target, to generate code for the 68332. Enclosed is a post that I kept
from the (helpful) people at CYGNUS describing this [you should check the
www.cygnus.com site too].

GCC does not use the addressing modes that exist on the 68020 but not 68332.
One can generate code for the 68332 using -m68020 -mnobitfield.
