Thanks.  Hmm, strange result...  Here both texlive for freebsd and
texlive for w32 don't remove ".." from the output, even when the current
directory is the root directory.  When the result doesn't contain
neither ":" nor ";", AUCTeX cannot know the right path delimiter.
Sorry, let me think for for a while.
