	PR fortran/91588
	* expr.c (check_inquiry): Remove extended component refs by
	using symbol pointers. If a function argument is an associate
	variable with a constant target, copy the target expression in
	place of the argument expression. Check that the charlen is not
	NULL before using the string length.
	(gfc_check_assign): Remove extraneous space.
