cpphash.c (CPP_IS_MACRO_BUFFER, [...]): Delete.

	* cpphash.c (CPP_IS_MACRO_BUFFER, FORWARD, PEEKC): Delete.
	(macro_cleanup): No need to cast pbuf->macro.
	(collect_expansion): Use _cpp_get_define_token.  Goto done if
	it returns VSPACE.  Remove check for trailing space after
	CPP_COMMENT.
	(_cpp_create_definition): Don't diddle flags here.  Return
	directly on error.
	(unsafe_chars): Handle c1 being EOF.
	(push_macro_expansion): Use unsafe_chars for both accidental-paste
	checks.  Don't push the buffer till after we're done with
	them.
	* cpplex.c (PEEKBUF, GETBUF, FORWARDBUF): New.
	(PEEKN, FORWARD, GETC, PEEKC): Use them.
	(cpp_push_buffer): Don't set new->alimit.  Set new->mark
	appropriately.
	(_cpp_parse_assertion): Don't NUL terminate.
	(_cpp_lex_token): Fix -traditional macro handling.  Don't skip
	hspace before calling _cpp_parse_assertion.  Remove all sets
	of only_seen_white. Treat '\f' as hspace.  Don't do anything
	special with '\n' here.
	(maybe_macroexpand): Handle T_EMPTY hash entries without
	pushing a buffer at all.
	(cpp_get_token): Handle clearing only_seen_white here.  Handle
	incrementing the line number here.  Clear
	potential_control_macro as well as only_seen_white, if
	appropriate.
	(cpp_get_non_space_token): Don't eat CPP_POP tokens.
	(_cpp_get_define_token): New function, basically like
	_cpp_get_directive_token was but doesn't eat horizontal space.
	Don't do anything with only_seen_white here.
	(_cpp_get_directive_token): Just call _cpp_get_define_token
	repeatedly till it returns non-hspace.

	* cpplib.c (PEEKN, FORWARD, GETC, PEEKC): Delete.
	(conditional_skip, skip_if_group): Return int.
	(DIRECTIVE_TABLE): Change origin of all conditional directives
	to "COND".
	(TRAD_DIRECT_P): New macro.
	(_cpp_handle_directive): Use _cpp_get_directive_token.  Issue
	an error for a bogus directive, unless -lang-asm.  Use
	TRAD_DIRECT_P. Loop calling handler functions till one returns
	zero.
	(get_macro_name): Don't diddle flags here.
	(do_define): Diddle flags here.  Use _cpp_get_directive_token.
	Create T_EMPTY nodes for #define macro /* nothing */.
	(do_undef): Don't copy the name.  Use _cpp_get_directive_token.
	Use hp->name when calling pass_thru_directive.
	(do_if, do_else, do_elif, do_ifdef, do_ifndef, conditional_skip):
	Return the result of conditional_skip and/or skip_if_group.
	Don't call _cpp_output_line_command.
	(consider_directive_while_skipping): Use _cpp_get_directive_token.
	Issue -Wtraditional warnings as appropriate.  Don't complain
	about unrecognized directives.  If we are to stop skipping,
	return the number of the directive that ended the skip.
	(skip_if_group): Use _cpp_get_directive_token.  Turn off macro
	expansion and line commands while skipping.  Return the result
	of consider_directive_while_skipping, if nonzero.
	(do_endif): Just set potential_control_macro here.
	(validate_else): Use _cpp_get_directive_token.
	(do_assert, do_unassert): Don't save pointers into the
	token_buffer across calls to the lexer.  Use
	_cpp_get_directive_token.

	* cpplib.h (cpp_buffer): Remove alimit and colno.  Make mark a
	pointer, not an offset.  Replace 'data', which was a generic
	pointer, with 'macro', which points to a struct hashnode.
	(cpp_reader): Add 'potential_control_macro' pointer.
	* cpphash.h (T_UNUSED): Replace with T_EMPTY.
	(CPP_BUF_GET, CPP_FORWARD): Delete.
	(CPP_IN_COLUMN_1, ADJACENT_TO_MARK): New macros.
	(CPP_IS_MACRO_BUFFER, CPP_SET_BUF_MARK, CPP_GOTO_BUF_MARK,
	ACTIVE_MARK_P): Update.
	(_cpp_get_define_token): New internal function.
	* cppfiles.c (read_include_file): Don't set fp->alimit or fp->colno.
