Try to detect when people are using one version of libguile and a

different version of ice-9.  People have been skewing things and
sending in bug reports.
* configure.in: Provide libguile its version information through a
separate header file generated by the Makefile, not through
scmconfig.h.
(GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION, GUILE_VERSION):
AC_SUBST these, instead of AC_DEFINE'ing them.
(GUILE_STAMP): New AC_SUBST: the time we configured the tree.
(AC_OUTPUT): Create ice-9/version.scm.
* acconfig.h (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
GUILE_VERSION): Deleted.
* Makefile.in: Regenerated.
