[M3commit] CVS Update: cm3

[Jay]

There is /something/ here but I don't understand what yet.
In particular, the m3/cm3cg code looks right, but the C code works better...
And none of the debugger options are particulary good. Time to give up and use printf I guess.
And I haven't had luck rebuilding cygwin1.dll from source either darn. :(

1) I need to double check that my commit comment is true.2) If it is, I'd strongly prefer static initialization without code, either asis, or by fixing the compiler...Having to run code for constant initialization is just lame..2b) If it isn't, I'll put it back.  - Jay
