	PR c/25309
	* c-typeck.c (struct spelling): Make I an unsigned HOST_WIDE_INT.
	(push_array_bounds): Delete prototype.  Change BOUNDS argument to
	an unsigned HOST_WIDE_INT.
	(print_spelling): Use HOST_WIDE_INT_PRINT_UNSIGNED to output the
	array index.
	(really_start_incremental_init): No need to call convert because
	bitsize_zero_node is already of type bitsizetype.
	(push_init_level): Extract the value of constructor_index as an
	unsigned HOST_WIDE_INT quantity, using tree_low_cst.
	(process_init_element): Likewise.

	* gcc.dg/large-size-array-2.c: New test case.
