80% of the compiler is platform independent. Only the codegenerator and
assembler parser and writers are CPU dependent.

A 64-bit PowerPC codegenerator needs to be written first. The compiler
itself is already 64-bit ready.
Multithreaded compiler is not usefull. It'll the compiler very complex and
less maintainable. Also the benefit is very small because of all the
