fix for __builtin_size_t

["Jan Beulich" <JBeulich at novell dot com>]

bootstrapped and tested on x86_64-unknown-linux-gnu.

2004-07-07 Jan Beulich <jbeulich@novell.com>

	* c-common.c (c_common_nodes_and_builtins): Use size_type_node
	instead of sizenode for __builtin_size_t.

testsuite:
2004-07-07 Jan Beulich <jbeulich@novell.com>

	* gcc.dg/builtin-size_t: New test for bogus warning when using
	__builtin_size_t.
	* gcc.dg/format/builtin_size_t: Dito.
