(top level)

	Merged from libada-gnattools-branch:
	2004-11-28  Nathanael Nerode  <neroden@gcc.gnu.org>

	* gnattools: New directory.
	* Makefile.def: Add gnattools as a module, depending on target-libada.
	* Makefile.in: Regenerate.
	* configure.in: Include gnattools in host_tools; disable it if ada
	is disabled.
	* configure: Regenerate.

(gcc)
	* configure.ac: Rename cc_for_cross_gnattools to host_cc_for_libada.
	* configure: Regenerate.
        * libada-mk.in: Remove CC; rename
	cc_for_cross_gnattools / cc_set_by_configure to host_cc_for_libada.

(gcc/ada)
	Partial merge from libada-gnattools-branch:

	2004-12-02  Nathanael Nerode  <neroden@gcc.gnu.org>
        * Makefile.in: Move gnattools{1,1re,2,3,4} and corresponding flags
        into code in gnattools/Makefile.in.  Remove direct dependencies on
        stamp-tools by tools clauses.
	2004-12-02  Nathanael Nerode  <neroden@gcc.gnu.org>
        * config-lang.in: Add gnattools to $lang_dirs.

(libada)
2004-12-03  Nathanael Nerode  <neroden@gcc.gnu.org>

	* Makefile.in: Add stamp file for building libada, to avoid
	duplicate builds every time all-gnattools is called.

2004-12-02  Nathanael Nerode  <neroden@gcc.gnu.org>

	* Makefile.in: Build gcc/ada/Makefile (by running gcc/ada/configure)
	here.

2004-08-16  Nathanael Nerode  <neroden@gcc.gnu.org>

	* configure.ac: Replace AC_CANONICAL_SYSTEM with _BUILD, _HOST,
	_TARGET.
	* configure: Regenerate.

2004-07-18  Nathanael Nerode  <neroden@gcc.gnu.org>

	* configure.ac, Makefile.in: Remove gnattools-specific code
	(see gnattools directory).
	* Makefile.in: Remove dead rts-* targets.
	* configure: Regenerate.

(gnattools)
2005-02-02  Nathanael Nerode  <neroden@gcc.gnu.org>

        * Makefile.in: Remove use of cc_set_by_configure; just use
        plain old CC from the top level in this case.

2005-01-30  Nathanael Nerode  <neroden@gcc.gnu.org>
	Merge from mainline at tag libada-gnattools-merge-20050129:
	* configure.ac: Changes propagated from gcc/ada/Makefile.in.
	* Makefile.in: Changes relocated from gcc/ada/Makefile.in.

2004-12-13  Nathanael Nerode  <neroden@gcc.gnu.org>

        * Makefile.in: Reinstate stamp-gnatlib check.

2004-12-02  Nathanael Nerode  <neroden@gcc.gnu.org>

	* Makefile.in: Inline gnattools{1,1-re,2,3,4} targets from
	gcc/ada/configure.ac into gnattools-native and gnattools-cross
	targets, collecting flags as appropriate from here,
	gcc/ada/Makefile.in, gcc/ada/configure.ac, etc.  Attempt to retain
	identical behavior.
	* configure.ac: Add necessary configure bits from
	gcc/ada/configure.ac.
	* configure: Regenerate.

2004-08-16  Nathanael Nerode  <neroden@gcc.gnu.org>

	* configure.ac: Replace AC_CANONICAL_SYSTEM with _BUILD, _HOST,
	_TARGET.  Replace _GCC_TOPLEV_NONCANONICAL_TARGET with
	ACX_NONCANONICAL_TARGET, and replace now-redundant AC_SUBST.
	* configure: Regenerate.

2004-07-18  Nathanael Nerode  <neroden@gcc.gnu.org>

	* Makefile.in, configure.ac: Remove libada-specific targets and
	variables.
	* configure: Regenerate.
	* New directory, cloned from libada.
