Will be fixed in a working LLVM on mingw.

And how does it do this?  By emulating Unix.

I don't know why you insist mingw isn't emulating Unix.  How else would
you describe software that allows Unix source to run on Windows with
little or no change?

Would you ever use mingw to create software that runs only on Windows
and never on Unix?

I think the $HOME and /etc assumptions are very limited in nature. Most 
of us who use LLVM every day here at UIUC don't need to bother 
installing anything in $HOME or /etc, and so they shouldn't be 
considered a major stumbling block for building a version of LLVM that 
runs on Windows, no matter how it is done or what libraries it is 
linked with.

Making it possible to build LLVM on mingw is a fine idea, and it has 
the added benefit of allowing us to reduce the dependencies on 
Unix/Linux libraries gradually. It seems likely that we'll want a 
non-mingw build at some point, but I don't see how they need to be 
mutually exclusive.

Patches are, as always, welcome.
