Just to make life more exciting, Cygwin implements its *own* symlink system on
the application level using one of several ways of storing them. SFU,
Microsoft's own Unix layer for Windows, does the same... differently. Yay.

Actually, you can just call lstat() and use S_ISLNK() on the result.

Incidentally, one minor bug report: because S_ISSOCK() and S_ISLNK() are
actually Posix extensions, if you try to compile with flags like
_XOPEN_SOURCE, then luafilesystem will break. I haven't quite tracked down
what's necessary to trigger this yet --- on Linux the API flag settings are a
horrible labyrinth of undocumented #ifdefs.
