[LLVMdev] Still can't compile backend or frontend on Windows

It's a shame this fine tool can't get better installation support for
Windows. If it did I suspect it would get a lot more coverage. After
5 months or so I still have no way to compile the backend tools let
alone the C frontend on windows. I have tried both Cygwin and Mingw so
far. MingW is preferrable since distributions of the binaries would not
require the cygwin.dll. It would be nice if the full backend binaries
under windows were available for download. I understand that the VC++
build has downloadable binaries somewhere, but it lacks the final
support for generating executable output (correct me if I'm wrong).
This time I attempted to compile the CVS version, 1.6 in the hope that
it had better support for Windows as some of the release notes seemed to
indicate. I followed the Mingw installation instructions on
http://www.geocities.com/henrik_bach_llvm/
There were a bunch of Warnings during the configure phase involving
missing utilities such as mmap and ldopen(). When I started make I died
with the following message:

(sigh) I thought operating system specific headers such as unistd.h
were not supposed to be needed. Perhaps someone who has successfully
compiled the backend under Windows using Mingw could point me to the
binary executables and/or even better some link libraries.
