        * configure.in (build_configargs, host_configargs, target_configargs):
        Remove build/host/target parameters.
        (host_libs): Add gmp and mpfr.
        (GMP tests): Reorganize to allow in-tree GMP/MPFR.
        * Makefile.def (gmp, mpfr): New.
        (gcc): Remove makefile target.
        * Makefile.tpl (build_os, build_vendor, host_os, host_vendor,
        target_os, target_vendor): New.
        (configure): Add host_alias/target_alias arguments.  Adjust invocations.
        * configure: Regenerate.
        * Makefile.in: Regenerate.

2007-01-11  Matt Fago  <fago@earthlink.net>

	* configure.in: Try to link to functions only in mpfr 2.2.x
        to improve robustness of configure tests.
	* configure: Regenerate.
