- All exported constants now have a prefix WM_
- Do not rely on FNM_* constants, use the WM_ counterparts
- Remove TRUE and FALSE to follow Git's coding style
- While at it, turn flags type from int to unsigned int
- Add an (unused yet) argument to carry extra information
so that we don't have to change the prototype again later
when we need to pass other stuff to wildmatch
