Use cpplib for cccp.

Wed Jun 10 13:41:23 1998  Dave Brolley  <brolley@cygnus.com>
	* cppmain.c (fatal): New function.
	* configure.in (cpp_main): New configuration variable.
	* configure: Regenerated.
	* Makefile.in (CCCP): Use a configuration variable to select base for cccp.
	(cppmain$(exeext)): Add @extra_cpp_objs@.
