     Here's a summary of the major problems:

	- Compiler crashes on some valid programs, sometimes crashing machine.  
  	  Most crashes are in the global optimizer.
	- Incorrect code generated in several cases.
	- INLINE unimplemented
	- M68020/030 support unimplemented.
	- Floating point coprocessor support unimplemented.
	- MPW shipped with compiler is pre-release MPW 3.2 and incomplete.
	- Manual is big but says little about the Mac implementation and
	  is basically a revision of the Zortech PC compiler manuals.
	

If you disable the global optimizer, (-O none), it's possible to get work done.
When the optimizer doesn't crash, it does a good job.  This product has
potential but really needed more testing before it shipped. 

      I look forward to the next release.

      If you have this compiler, send Zortech bug reports.  They react
to bug reports, but seem to be weak on internal testing capability.
