	* macro.c: Delete unnecessary function declarations.
	(buffer_and_nest): Support multiple labels per line for
	LABELS_WITHOUT_COLONS targets if the labels do have colons.
	(free_macro): Move so that we don't need forward declaration.
	* read.c (read_a_source_file): Take a copy of macro expansion line
