Perhaps not.  It was really just an experiment: everybody including me 
has been claiming that "just build a real cross-compiler; that's 'the 
right way to do it'"

so I gave it a shot.

It wasn't as easy as everyone thought.  Lots of weirdness (mostly in 
directory layout) to make it coexist peacefully with the mingw bits of 
cygwin.

Probably.

No, I think you made the right choice.  Besides, my cross compiler goes 
into /opt/mingw/* -- so no conflict there.  Also, if one were to install 
mingw itself, it goes into /mingw.

I'll look for it -- it's not in my "normal" sources, so I guess normal 
sources use a default definition from somewhere else.  I'll download 
your gcc2-src package and use that...

Ah.  But if you munge the filenames at install time, then don't stage2 
and stage3 break?

Agreed -- I actually LIKE the -2 distinction.
