I am not aware of anyone who regularly build LLVM/clang with MSVC 2005
so you might run into some problems.

I suggest you update to MSVC 2010 (or 2008 will do). There is a
buildbot for MSVC 2010 so issues are generally fixed quite fast. Also
LLVM compile just fine if you use the free MSVC Express edition so
having to pay for a license should not be problem.
