Subject: [PATCH] configure.in: Simplify use of AC_CACHE_SAVE.

2000-10-29  Benjamin Kosnik  <bkoz@redhat.com>

	* configure.in: Simplify use of AC_CACHE_SAVE.  Put linked files
	in $(top_builddir)/include/bits, not $(top_builddir)/bits, to help
	with libgcj build issues and improve consistency with the source
	directory's include directory setup.
	* configure: Regenerate.
	* acinclude.m4: Same here.
	* aclocal.m4: Regenerate.
	* mknumeric_limits (OUT_H): Also change paths here.
	* mkcheck.in (C_DIR): And here.
	* mkc++config (OUT_H): And here.
	* libmath/Makefile.am (INCLUDES): And here.
	* src/Makefile.am (INCLUDES): Change to $(top_builddir)/include.
	* libio/Makefile.am: Ditto.
	* libsupc++/Makefile.am (INCLUDES): Ditto.
