lex.c: (handle_sysv_pragma): FILE* parameter not used.

Thu May 21 11:54:44 1998  Dave Brolley  <brolley@cygnus.com>
	* lex.c: (handle_sysv_pragma): FILE* parameter not used.
	(cpp_reader,parse_in): Add for cpplib.
	(check_newline): Call handle_sysv_pragma with new interface.
	(check_newline): Call GET_DIRECTIVE_LINE, not get_directive_line.
	* input.c: (yy_cur,yy_lim,yy_get_token,GETC): Add for cpplib.
	(sub_getch): Call GETC for cpplib.
	* cp-tree.h: (get_directive_line): Different prototype for cpplib.
	(GET_DIRECTIVE_LINE): Macro wrapper for get_directive_line.
	* Makefile.in (CXX_OBJS): add @extra_cxx_objs@ for cpplib.
