How can you tell what header files clang is using ? I built clang using 
MSYS in a directory outside of my llvm/clang structure. If I include C++ 
standard library header files when compiling a source file with clang, 
how do I determine where clang is searching for those header files ?

Is there a 64-bit version of clang ? If so, how does one build the 
64-bit version under MSYS/MingW in Windows ?
