Is the file you're lstat'ing a symlink? The point of lstat is that it gives
you the stat structure for the -symlink-, if the file is a symlink. If the
file you're lstat'ing is a symlink to a directory the -d test is still going
to fail, because the stat structure reflects the symlink itself (and, for
obvious reasons, a symlink isn't a directory). The stat() operator returns
the stat structure for the file the symlink points to.
