[LLVMdev] size_t?

[Eric Mader]

Hi Reid,

I copied the x64 toolsets by hand; they got installed to C:\Program 
Files (x86)\LLVM\tools\msbuild\x64; they just didn't get moved correctly 
by install.bat.

I just verified that the LLVM-vs2013 toolset.props is correct.

If it is a bitness problem, perhaps I'm failing to define something 
correctly?

Regards,
Eric
