+       Make fflush-after-ungetc POSIX compliant on BSD systems.
+       * lib/fflush.c (clear_ungetc_buffer_preserving_position): New function.
+       (clear_ungetc_buffer): Implement also for other systems.
+       (rpl_fflush): On glibc systems, invoke
+       clear_ungetc_buffer_preserving_position. Otherwise, invoke
+       clear_ungetc_buffer after fetching the stream's position, not before.
