      2005-12-22  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/20889
	*resolve.c(resolve_structure_cons): Do not attempt to convert
	the type of mismatched pointer type components, except when
	the constructor component is BT_UNKNOWN; emit error instead.

	PR fortran/25029
	PR fortran/21256
	*resolve.c(check_assumed_size_reference): New function to check for upper
	bound in assumed size array references.
	(resolve_assumed_size_actual): New function to do a very restricted scan
	of actual argument expressions of those procedures for which incomplete
	assumed size array references are not allowed.
	(resolve_function, resolve_call): Switch off assumed size checking of
	actual arguments, except for elemental procedures and array valued
	intrinsics; excepting LBOUND.
	(resolve_variable): Call check_assumed_size_reference.

	PR fortran/19362
	PR fortran/20244
	PR fortran/20864
	PR fortran/25391
	*interface.c(gfc_compare_types): Broken into two.
	(gfc_compare_derived_types): Second half of gfc_compare_types with
	corrections for a missing check that module name is non-NULL and
	a check for private components.
	*symbol.c(gfc_free_dt_list): New function.
	(gfc_free_namespace): Call gfc_free_dt_list.
	*resolve.c(resolve_symbol): Build the list of derived types in the
	symbols namespace.
	*gfortran.h: Define the structure type gfc_dt_list.  Add a new field,
	derived_types to gfc_namespace.  Provide a prototye for the new
	function gfc_compare_derived_types.
	*trans_types.c(gfc_get_derived_type): Test for the derived type being
	available in the host namespace. In this case, the host backend
	declaration is used for the structure and its components.  If an
	unbuilt, equal structure that is not use associated is found in the
	host namespace, build it there and then.  On exit,traverse the
	namespace of the derived type to see if there are equal but unbuilt.
	If so, copy the structure and its component declarations.
	(copy_dt_decls_ifequal): New functions to copy declarations to other
	equal structure types.

	PR fortran/20862
	* io.c (gfc_match_format): Make the appearance of a format statement
	in a module specification block an error.

	PR fortran/23152
	* match.c (gfc_match_namelist): Set assumed shape arrays in
	namelists as std=GFC_STD_GNU and assumed size arrays as an
	unconditional error.

	PR fortran/25069
	* match.c (gfc_match_namelist): Set the respecification of a USE
	associated namelist group as std=GFC_STD_GNU.  Permit the concatenation
	on no error.

	GFC_STD_GNU and change message accordingly.  Add same error for
	SIZE.
	(match_dt_element, gfortran.h): Add field err_where to gfc_dt and
	set it when tags are being matched.
	(gfc_resolve_dt): Remove tests that can be done before resolution
	and add some of the new ones here.
	(check_io_constraints): New function that checks for most of the
	data transfer constraints. Some of these were previously done in
	match_io, from where this function is called, and some were done
	in gfc_resolve_dt.
	(match_io): Remove most of the tests of constraints and add the
	call to check_io_constraints.
