Sounds good! As for documentation, I think we'd be sticking to HTML,
since it's the most accessible form for everyone.

Sounds good! I'm not sure how to put those into gcc, but we can all take
a look. The official gcc page is at
http://www.gnu.org/software/gcc/gcc.html and there are documents
describing the compiler internals. If you have trouble with those, I
might be able to help, I've been through them once before.

That would be good. Any further support is good, although there might be
support there already, I'm not sure.

You can pick which you prefer, I run on Mac OS X. For Win32, you'll need
Cygwin. Not sure where to find it, or how to install it, though.
