I would imagine most Ada compilers (even crappy ones) take at least 10
man-years
to complete. It really isn't a project for a single person. Yes, I have made
a start of it (on the late, great, Amiga). Completing the lexer alone would
have
taken me over a month. The parser? <shudder>

You're crazy.

Uhh, unless I'm mistaken, GNAT is available for the MAC. If it doesn't exist
for
the MAC, porting it WOULD be a job one person could accomplish. You might want
to consider that instead of building your own from scratch.

If you really want to build your own compiler as an exercise, why not try 
something smaller?

Good luck, and I'm sorry I was so negative.
