2005-01-21  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/25124
	PR fortran/25625
	* decl.c (get_proc_name): If there is an existing
	symbol in the encompassing namespace, call errors
	if it is a procedure of the same name or the kind
	field is set, indicating a type declaration.

	PR fortran/20881
	PR fortran/23308
	PR fortran/25538
	PR fortran/25710
	* decl.c (add_global_entry): New function to check
	for existing global symbol with this name and to
	create new one if none exists.
	(gfc_match_entry): Call add_global_entry before
	matching argument lists for subroutine and function
	entries.
	* gfortran.h: Prototype for existing function,
	global_used.
	* resolve.c (resolve_global_procedure): New function
	to check global symbols for procedures.
	(resolve_call, resolve_function): Calls to this
	new function for non-contained and non-module
	procedures.
	* match.c (match_common): Add check for existing
	global symbol, creat one if none exists and emit
	error if there is a clash.
	* parse.c (global_used): Remove static and use the
	gsymbol name rather than the new_block name, so that
	the function can be called from resolve.c.
	(parse_block_data, parse_module, add_global_procedure):
	Improve checks for existing gsymbols.  Emit error if
	already defined or if references were to another type.
	Set defined flag.

	PR fortran/PR24276
	* trans-expr.c (gfc_conv_aliased_arg): New function called by 
	gfc_conv_function_call that coverts an expression for an aliased
	component reference to a derived type array into a temporary array
	of the same type as the component.  The temporary is passed as an
	actual argument for the procedure call and is copied back to the
	derived type after the call.
	(is_aliased_array): New function that detects an array reference
	that is followed by a component reference.
	(gfc_conv_function_call): Detect an aliased actual argument with
	is_aliased_array and convert it to a temporary and back again
	using gfc_conv_aliased_arg.
