'configure' is supposed to detect that you're using zsh, and to work
around the incompatibilities.  The code to do this is at the very
start of 'configure', as follows:

   # Be Bourne compatible
   if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then
     emulate sh
     NULLCMD=:
   elif test -n "${BASH_VERSION+set}" && (set -o posix) >/dev/null 2>&1; then
     set -o posix
   fi

Can you please try autoconf 2.52g:
ftp://alpha.gnu.org/gnu/autoconf/autoconf-2.52g.tar.gz

and if that doesn't work, find out why the above code does not work on
MacOS X?  For example, perhaps ZSH_VERSION isn't set in MacOS X; or
perhaps 'emulate sh' does not work.  Thanks.
