I see what's happening. This code here...


...sets st.filetype to PHYSFS_FILETYPE_SYMLINK and fails out.

There's several ways to do "symlinks" on Windows; if they do an NTFS 
junction point, it's sort of like a symlink, but not quite, and it'll 
pass the test that check.


...which leads to it skipping this "if" to the next "else if" where it 
declares it's actually a directory, and everything happens to work.
