	* cpperror.c (print_file_and_line): If line is (unsigned int)-1,
	print just the filename.
	* cpplex.c (_cpp_run_directive): Add additional argument, the

	translated "<command line>".
	* cpplib.c (cpp_define, cpp_undef, cpp_assert, cpp_unassert):
	Adjust to match.
	(_cpp_define_builtin): New function.
	* cppinit.c (initialize_builtins): Use _cpp_define_builtin.
	* cpphash.h: Update prototypes.

	* tradcpp.c (main): Process -D and -U simultaneously, in the
	order they appeared on the command line.
