	* cppexp.c (parse_charconst): Initialize c.
	(cpp_parse_expr): Initialize rprio.
	* cppfiles.c (merge_include_chains): Initialize prev.
	(finclude) Set fp->line_base to fp->buf before returning.
	* cpphash.c (macroexpand): Initialize token.
	* cppspec.c (lang_specific_driver): Change suff to
	const char *const *.
