OK, I installed the following patch.  It should appear in the next
Autoconf version.  (Personally, I think all shells that use ';' as a
separator should be taken out and shot, but that's not your problem.  :-)

        * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
        Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
        apparently treats PATH="nonexistent" as if it contained ".".
