Fix various data type problems
- Make sure the mockup constant for AT_FDCWD is actualy an int
- Don't use %lld printf format specified, mscrt doesn't have that
- On 64 bit windows, use %I64u format specified for size_t
- Seperate the overflow macro stuff from the form specifier stuff
- Move the whole thing to compat.h and clean it up a little so
it becomes readable.
