[LLVMdev] Working on getting MingW32/native tools-only source build up

Don't do this. Use either pure cygwin or pure mingw (with msys + msysDTK) 
installation. This will save bunch of time for you. Seriously.

See upper.

Well. This can be gcc/binutils bug or something like this. I prefer to
be conservative and can declare, that everything is ok with gcc 3.4.5
and recent binutils available from mingw website.
