re PR fortran/31215 (ICE on valid code with gfortran)

2007-03-24  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/31215
	* trans-expr.c (gfc_apply_interface_mapping_to_expr): Return
	int result that is non-zero if the expression is the function
	result.  Only the characteristics of the result expression
	can be used in a procedure interface, so simplify LEN in situ
	using its character length.

	PR fortran/31219
	PR fortran/31200
	* trans-expr.c (gfc_conv_function_call): Do not use
	gfc_conv_expr_reference for actual pointer function with formal
	target because a temporary is created that does not transfer
	the reference correctly.  Do not indirect formal pointer
	functions since it is the function reference that is needed.
