Has anybody successfully build Mesa 7.10 with llvmpipe driver using LLVM 2.8 on Windows

Has anybody successfully build Mesa 7.10 with llvmpipe driver using LLVM 2.8 on Windows with the Visual Studio 2010 toolchain?

The official release files contain no SConscript, so I got the 7.10 branch from their git repository and tried to build it. I get weird link errors about __fopen, __exit and other standard libraries.

Update:
Got the problem. Both had to compile with the same runtime libraries, but LLVM was compiled with MD and Mesa with MT. So I switched both to MT. But still have a problem – it gives me a link error about __va_copy. I can see it is called from the Mesa code, and the code compiles properly but DOES NOT LINK. I don’t understand why :/

    va_copy is not provided by all compilers. You might get away with adding a simple #define macro in the mesa code. See va_copy — porting to visual C++? for a discussion about va_copy.
