[LLVMdev] Build Clang and LLVM on Win 8

[Giorgio Franceschetti]

On my PC it does not work.

I'm able to generate and open the Visual studio project (VS 11 Win64).

I have tried with cmake on command line, with the cmake gui, release 3.4 
and 3.3.

But when I try to compile the solution I get a loot of errors about a 
missing stdbool.h file.

Does anyone have any hint?
