Thanks. I'll try some of this. Further comments in-line:

Say, that sounds plausible.

With forward-slashes? or back-slashes? (I'll try both if I have to :)

I don't know. At this poin I'm just trying lots of stuff. :-)

I don't know either. I believe I tried the bootstrap flag at one point,
but still no dice. Last weekend, I actualy did build gcc (*not* llvm-gcc)
successfully which proved to me that there wasn't something fundamentally
wrong with my MinGW setup. The build went smoothly using a script I
snagged off the MinGW WIKI. This is what prompted me to start my own
script.
