12816 * cpphash.h (struct cpp_buffer): Restore return_at_eof field. This
12817 partly reverts my 2003-10-01 change, because we're back to logically

12831 which is set also for (say) <command line>. Clear print.first_time.
12833 * cppfiles.c (struct _cpp_file): Comment and type for pch field
12834 does not match the code, so fix both.
