Build config:
- MS Visual Studio 2013 Update 5
- LLVM 3.9 (last version supporting VS2013)

- Built with -MT CRT threading option.

Scons command line:

scons build=release texture_float=True llvm=yes platform=windows machine=x86
gallium opengl32

NOTES:

Reverting commit 73f1e33d34b2044f2252a73e0fdd827d39724505 and applying the
patch proposed in commit 9d220fa950850d751fbbbc2cd4ec24d024fcad70 fixes the
compile.  However, as of writing, the resultant binary has not been tested.
