configure.in (extra_c_objs): add prefix.o.

Thu May 21 11:51:15 1998  Dave Brolley  <brolley@cygnus.com>
	* configure.in (extra_c_objs): add prefix.o.
	(extra_cxx_objs): extra objects for C++ with cpplib.
	* configure: Regenerate.
	* c-tree.h: (get_directive_line): Different prototype for cpplib.
	(GET_DIRECTIVE_LINE): Macro wrapper for get_directive_line.
	* c-lex.h: (get_directive_line): Not needed here for cpplib.
	* c-lex.c: (yy_cur,yy_lim,yy_get_token): Move to c-common.c.
	(GET_DIRECTIVE_LINE): Move to c-common.c and rename to get_directive_line.
	* c-common.c (parse_in,parse_options,cpp_token): Declare for cpplib.
	(yy_cur,yy_lim,yy_get_token,get_directive,line): Moved here from c-lex.c
