I am currently working on a 68360 project and would like very much to
get us off of a proprietary compiler, primarily so that the Pentium,
Sparc, 68340, 68360, and PPC cpus would all use the same compiler
front end and libraries.  It would be nice to switch to RTEMS someday
also, but first I want to do the compiler.
