The small patch below is needed to make it compilable again. Do you
have some good use cases to test it with? Just starting it in ascii
mode gives a segmentation fault when generating the first move, but I
don't know whether it's expected to work.

From a 2002 message I dug up:

| gnugo -l ManyFaces3-gnugo-3.3.11-200211071935.sgf -L25

|

This does still work, although it no longer finds C14.
