re PR fortran/54286 (Accepts invalid proc-pointer assignments involving proc-ptr function result)

2013-01-13  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/54286
	* expr.c (gfc_check_pointer_assign): Ensure that both lvalue
	and rvalue interfaces are presented to gfc_compare_interfaces.
	Simplify references to interface names by using the symbols
	themselves. Call gfc_compare_interfaces with s1 and s2 inter-
	changed to overcome the asymmetry of this function. Do not
	repeat the check for the presence of s1 and s2.

	PR fortran/54286
	* gfortran.dg/proc_ptr_result_8.f90 : New test.
