And it really is that small, file functions of the Win32 API cannot handle longer paths. However, there is a (pretty ugly, if you ask me) workaround: prefixing the paths with "\\?\" and lo and behold, *many* (but not all) Win32 API functions can then handle paths up to something around 32,000 characters! The problem Karsten addressed here is caused exactly by this oddity: we *can* handle paths much longer than PATH_MAX. Therefore, we need to decouple the path buffers from that hardcoded limitation. Karsten, you rock.
