d68bd5a8f2 re PR fortran/25056 (non-PURE function should not be a valid argument)
2006-06-25  Paul Thomas  <pault@gcc.gnu.org>
 
	PR fortran/25056
	* interface.c (compare_actual_formal): Signal an error if the formal
	argument is a pure procedure and the actual is not pure.

	PR fortran/27554
	* resolve.c (resolve_actual_arglist): If the type of procedure
	passed as an actual argument is not already declared, see if it is
	an intrinsic.

	PR fortran/25073
	* resolve.c (resolve_select): Use bits 1 and 2 of a new int to
	keep track of  the appearance of constant logical case expressions.
	Signal an error is either value appears more than once.

	PR fortran/20874
	* resolve.c (resolve_fl_procedure): Signal an error if an elemental
	function is not scalar valued.

	PR fortran/20867
	* match.c (recursive_stmt_fcn): Perform implicit typing of variables.

	PR fortran/22038
	* match.c (match_forall_iterator): Mark new variables as
	FL_UNKNOWN if the match fails.

	PR fortran/28119
	* match.c (gfc_match_forall): Remove extraneous call to
	gfc_match_eos.

	PR fortran/25072
	* resolve.c (resolve_code, resolve_function): Rework
	forall_flag scheme so that it is set and has a value of
	2, when the code->expr (ie. the forall mask) is resolved.
	This is used to change "block" to "mask" in the non-PURE
	error message.

	arrays have constant bounds to those in the main program.  At the
	same time simplify the array bounds, to avoiding trapping parameter
	array references, and exclude automatic character length from main
	and modules. Rearrange resolve_symbol and resolve_derived to put as
	each flavor together, as much as is possible and move all specific
	code for flavors FL_VARIABLE, FL_PROCEDURE and FL_PARAMETER into new
	functions.
	(resolve_fl_var_and_proc, resolve_fl_variable, resolve_fl_procedure):
	New functions to do work of resolve_symbol.
	(resolve_index_expr): New function that is called from resolved_symbol
	and is extracted from resolve_charlen.
	(resolve_charlen): Call this new function.
	(resolve_fl_derived): Renamed resolve_derived to be consistent with
	the naming of the new functions for the other flavours.  Change the
	charlen checking so that the style is consistent with other similar
	checks. Add the generation of the gfc_dt_list, removed from resolve_
	symbol.
