Please note, that these binaries weren't built from original 1.9 sources.
There were several post-1.9 patches in LLVM & llvm-gcc4 trees, fixing some
mingw32 target related issues.

As it's quite tricky to build llvm-gcc4 for mingw32 target (common problem
with gcc build process on windows), it isn't good just to say people "get 
sources from CVS head and build". Instead, it was desided to grab some
importand patches from current trunk, apply them to 1.9 tree and build new
binaries.

List of patches applied can be found in the "patches" directory. I'll try
to monitor necessary patches and update binaries.
