I'm glad that someone found my hackery useful!

In a word: hell, no!  (Ok, two words.)

It sure is--type safety?  What a laugh.

: Second and more serious the compiled code only runs on a powerpc and not

I seem to remember this always being the case with my patches--the whole point
was to get Common Lisp code to compile on the PowerMac in some form, since at
that time there was an ENORMOUS broughaha over the idea that MCL would not go
native.

: Has anybody else tried Clicc 0.6.4 in  Codewarrior 5? I would need some
: support since I am not very familiar with C programming on the Mac and the
: differences between an 68K and a PowerPc.

Well, you've caught the attention of the guy who did the original 0.6.2 work.
Where could I find your diffs to the 0.6.4 release?
