* c-common.h (enum c_tree_index): Add CTI_SIGNED_SIZE_TYPE and

	CTI_UNSIGNED_PTRDIFF_TYPE.
	(signed_size_type_node): Define.
	(unsigned_ptrdiff_type_node): Define.
	* c-decl.c (init_decl_processing): Create the
	signed_size_type_node and unsigned_ptrdiff_type_node types.
	* c-common.c (T_SC): Define.
	(T_SST): Define.
	(T_UPD): Define.
	(print_char_table): Use T_SST for %zd, %zi, %zn.  Use T_UPD for
	%to, %tu, %tx, %tX.  Allow %hhn (T_SC).  Add "c" to the flags for
	%s and %p.
	(scan_char_table): Use T_SC for %hhd, %hhi, %hhn.  Use T_SST for
	%zd, %zi, %zn.  Use T_UPD for %to, %tu, %tx, %tX.  Add "c" to the
	flags for %c, %s and %[.
	(check_format_info): Only allow leniency for signedness of targets
	of character pointers (when pedantic) for formats flagged with
	"c", so for strings but not for %hh formats.  When pedantic, don't
	allow character pointers to substitute for void pointers if a
	second level of indirection is present.

testsuite:
	* gcc.dg/c99-printf-1.c: New test.
