0.9.16.46:
        Fix regressions:

        * Installation was broken with non-bash /bin/sh (thanks to
          Niimi Satoshi for the patch)
        * DEFAULT-EXTERNAL-FORMAT would now try to print a warning for
          an invalid external format before streams had been initialized,
          causing an infinite error loop (reported by Hannu Koivisto).
          Temporary fix is just not printing the warning, a better fix
          will wait until after the freeze.
        * Also stop autodetecting the external format from the locale
          on non-unicode builds. Having a default external format that's
          incompatible with CHARACTER doesn't seem very sensible, especially
          now that the external formats are also used for SB-ALIEN:C-STRING
          instead of just streams.
