	* cpphash.c (dump_definition): New function.
	* cpphash.h: Prototype it.
	
	* cpplib.c (handle_directive): Don't output anything here.
	Streamline.
	(pass_thru_directive): Take a length, not a pointer to the
	end.  All callers changed.
	(do_define): Handle -dD, -dN, -g3 entirely here.  Streamline.
	(do_include): Handle -dI here.
	(do_ident): Correct to match cccp.
	(do_pragma): Copy the pragma through here.
	(do_assert, do_unassert): Tidy.
	
	* cppinit.c (cpp_finish): If -dM was specified, walk the macro
	hash table and call dump_definition on all the entries.
	* cppmain.c: cpp_finish may produce output.
