[LLVMdev] Undefined referenceto`llvm::sys::CopyFile(llvm::sys::Path const&, llvm::sys::P

[Jeff Cohen]

But breaks VC++.

The problem is, Windows.h defines "CopyFile" as a macro that's either 
"CopyFileA" or "CopyFileW".  Path.h is included before Windows.h, so the 
declaration has the name "CopyFile" while the definition has 
"CopyFileA".  Instant compilation error.

Not sure what the best way to fix it is, but I'll check it in as soon as 
I figure it out.
