Log message:
	2000-07-11  Zack Weinberg  <zack@wolery.cumb.org>
	
	* cpplex.c (parse_name): No longer inline (premature optimization).
	(do_pop_context): Fold into pop_context.
	(pop_context): Returns int.
	(lex_next): Hoist test for end of directive into pop_context.
	(push_macro_context): Returns int; takes just reader and token.
	Hoist test for excessive nesting to caller.
	(push_arg_context): Returns void; takes just reader and token.
	Do not call stringify_arg or get_raw_token.
	(get_raw_token): Convert tail recursion through	push_arg_context
	to a loop at this level.  Call stringify_arg here if appropriate.
	(maybe_paste_with_next): Convert tail recursion to a while loop.
	Hoist test of paste_level to caller.
	
	(stringify_arg): Push arg context at beginning.
	(cpp_get_token): Split out core into _cpp_get_token.  Call
	process_directive here.  Throw away CPP_PLACEMARKER tokens.
	(_cpp_get_token): Convert tail recursion through
	push_macro_context to a loop at this level.
	(_cpp_glue_header_name, is_macro_disabled, stringify_arg,
	_cpp_get_raw_token): Use _cpp_get_token.
	(_cpp_skip_rest_of_line): Drop the context stack directly; do
	not call pop_context.
	(_cpp_run_directive): Call lex_next directly.
	
	* cpphash.h: Prototype _cpp_get_token.
	* cppexp.c (lex): Use it.
	* cpphash.c (parse_define): Use it.
	* cpplib.c (get_define_node, do_undef, parse_include,
	read_line_number, do_line, do_ident, do_pragma, do_pragma_gcc,
	do_pragma_implementation, do_pragma_poison, do_pragma_dependency,
	parse_ifdef, validate_else): Use it.
	(cpp_push_buffer): Tweak error message; abort if anyone tries
	to push a buffer while macro expansions are stacked.
	
	2000-07-11  Donn Terry  <donnte@microsoft.com>
	
	* cpplex.c (free_macro_args, save_token): Cast arg of free
	and/or xrealloc to PTR.
	(_cpp_init_input_buffer): Clear all fields of the base context.
