Thanks for tracking this down.  This is due to an incompatibility of
zsh with POSIX shells.  I installed this patch into the Automake and
Autoconf main branches.


2004-12-08  Paul Eggert  <address@hidden>

        * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
        the spaces inside $ls_command.  Problem reported by Loulou Pouchet in
        <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
        Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
