Hmm, looking at the configure.in script, it seems you're right.
I wonder why this weird dependency on TCL was added. This was
certainly not intended (see the comment):

if test $enable_unicode = yes
then
  # Without any arguments, Py_UNICODE defaults to two-byte mode
  case "$have_ucs4_tcl" in
  yes) enable_unicode="ucs4"
       ;;
  *)   enable_unicode="ucs2"
       ;;
  esac
fi

The annotiation suggests that Martin added this.

Martin, could you please explain why the whole *Python system*
should depend on what Unicode type some installed *TCL system*
is using ? I fail to see the connection.

Thanks,
