I know why msvc broken:(

I have already meet the problem before:)
It's just because the installation of MSVC 2008 sp1.
If you don't downgrade sp1, then we can using nmake system
for example.
%BLD%\cmake\bin\cmake.exe -DPYTHON_EXECUTABLE=%BLD%/python/python.exe
-DCMAKE_INSTALL_PREFIX=%BLD%/llvm -G "NMake Makefiles" D:/svn/llv

And it's must be working:)
At lease on my computer is working:)
