Re: Use the pathsep deduced by autoconf

I disagree with this patch.  Using Autoconf's PATH_SEPARATOR is fine,
it's documented and will be maintained.  Do not depend on private
undocumented variables such as ac_path_separator.  FYI, it will
disappear since that code will move into M4sh.

Never ever *EVER* use an Autoconf private variable.

Autoconf itself should use PATH_SEPARATOR only, thanks for the bug
report ;)
