This weekend I compiled LLVM and clang under Cygwin. I had a problem
compiling both of them for the same reason: Cygwin maps the *int32_t
types to longs instead of ints. I have submitted a fix for LLVM, but
for clang I punted with these heavy-handed casts:

I suspect that someone who knows this code better could come up with a
