[Bug-gnubg] new bearoff databases

[Ned Cross]

I just installed Nardy's 021129 build, using the new bearoff db,running Windows ME.

 

Something's not right, as shown by this example where GNU doubles as a huge underdog. The equities are nowhere close to the valuse provided by GNUBG build 021119, and the output doesn't read the file correctly, thinking the cube was passed, when it was taken.  I've attached the .sgf and the text output from build 021119 for comparison.

 

(my GNUBG installs into directory c:\program files\backgammon\gnubg, and that's where I extracted the gnubg_ts0.bd file).
