[Rob Browning]

Changing GUILE-VERSION doesn't update these deriviative files.  This
patch may fix that:

Subject: [PATCH 1/1] Ensure GUILE-VERSION changes propagate to .version and
 Makefiles

Have .version depend on the Makefile, and move our
CONFIG_STATUS_DEPENDENCIES setting to an AC_SUBST, as recommended by the
automake info pages "Rebuilding Makefiles" section, so that changes to
GUILE-VERSION will update the VERSION, etc. in the generated Makefiles.

* Makefile.am (CONFIG_STATUS_DEPENDENCIES): drop.
($(top_srcdir/.version)): depend on Makefile.
* configure: add GUILE-VERSION to CONFIG_STATUS_DEPENDENCIES via
AC_SUBST.
