--enable-multibyte dies (UnixWare 7.1.1)/Current Sources

Tried --enable-multibyte for grins. Bad Move.

Top part of config.status:
#! /bin/sh
# Generated automatically by configure.
# Run this file to recreate the current configuration.
# This directory was configured as follows,
# on host lerami.lerctr.org:
#
# ./configure --prefix=/home/ler/pg-test --enable-syslog --with-CXX --with-perl --enable-multibyte --with-includes=/usr/local/include --with-libs=/usr/local/lib
#
# Compiler output produced by configure, useful for debugging
# configure, is in ./config.log if it exists.

Bottom of make output...
