	* cpplib.c: Don't include signal.h, sys/times.h, or
	sys/resource.h. Don't declare localtime.
	(macroexpand): Handle special symbols here.
	(push_macro_expansion): Chop off the trailing '@ ' if possible
	here.
	(cpp_get_token): Don't do either of the above two things here.
	Move `string' label just after case '"' so that wide strings
	don't crash the preprocessor.
