ccc - full native C compiler -------- this is very far from working ----------

i wrote this about a dozen years ago and lost the source. I am typing it in from a paper printout with a few missing chunks, so it will be a while before it works.

this is a 2 pass compiler.

the first pass is a recursive descent parse with embedded CPP. it writes an ascii parse tree file.

the second pass is a code generator and assembler. it writes an object file
