    Preserve ACLOCAL_PATH in later builds, so that by default it has
    the same value as it did in the first build after initial checkout.
    * Makefile.in (ACLOCAL_PATH): New macro.
    ($(srcdir)/aclocal.m4): Use it.
    * configure.ac (ACLOCAL_PATH): AC_SUBST it.
    * autogen.sh (env_space): New var.
    Tell user what variables, if any, to pass to 'configure'.
