	* cpphash.c: Don't include hashtab.h.  Most macro-handling code
	moved to cppmacro.c.
	(hash_HASHNODE, eq_HASHNODE, _cpp_dump_macro_hash,
	dump_hash_helper): Delete.
	(expand_hash, higher_prime_number, _cpp_lookup_with_hash,
	cpp_forall_identifiers): New. Implement specialized version of
	Vlad's expandable hash table.
	(cpp_lookup): Use new functions.
	(_cpp_init_macros, _cpp_cleanup_macros): Adjust for new
	implementation.
	* cppmacro.c: New file.
	* cppinit.c (dump_macros_helper): New.
	(cpp_finish): Iterate over the identifier table directly.
	* cpplex.c (parse_name): Calculate the hash of the identifier
	while we scan it.  Use _cpp_lookup_with_hash when we can.

	* cpphash.h: Update prototypes.
	(xcnewvec, HASHSTEP): New helper macros.
	* cpplib.h: Update prototypes.
	* Makefile.in (LIBCPP_OBJS): Add cppmacro.o.
	(cppmacro.o): New rule.
	(cpphash.o): Update deps.

	* cppmain.c: Do not set pfile->printer if no_output is on.

	* cpplib.c: Change all directive-handler functions to return
	void, not int.
	* cpphash.h: Update typedefs.
