2018-02-12  Thomas Koenig  <tkoenig@gcc.gnu.org>

	* libgfortran.h (GFC_ARRAY_DESCRIPTOR): Remove dimension
	of descriptor to use vaiable members for dim.
	Change usage of GFC_ARRAY_DESCRIPTOR accordingly.
	(GFC_FILL_ARRAY_DESCRIPTOR): New macro.
	(gfc_full_array_i4): New type.
	* intrinsics/date_and_time.c (secnds): Use sizeof
	(gfc_array_i4) + sizeof (descriptor_dimension) for memory
	allocation.
	* intrinsics/reshape_generic.c: Use GFC_FULL_ARRAY_DESCRIPTOR.
	* io/format.c: Use sizeof (gfc_array_i4) + sizeof
	(descriptor_dimension) for memoy allocation.
	* io/list_read.c (list_formatted_read_scalar): Use
	gfc_full_array_i4 for variable.
	(nml_read_obj): Likewise.
	* io/write.c (list_formatted_write_scalar): Likewise.
	(nml_write_obj): Likewise.
	* m4/reshape.m4: Use GFC_FULL_ARRAY_DESCRIPTOR.
