Yes, in 10 years of development on NeXTSTEP, OPENSTEP, now Mac OS X, 
I've never seen this. I don't know enough about compilers or gcc to 
decide if this a bug though.

If anyone cares, cc -v gives:
Apple Computer, Inc. version gcc-934.3, based on gcc version 2.95.2 
19991024 (release)

Yes, declaring it static fixes the problem. I'm not familiar with 
contributing code or patches to gnugo, so could please one of you guys 
fix it? Thanks.
