Dann Corbit made a windows version here:

Thanks Sergio for the finding and Dann for the compile

After a quick test under Winboard, it appears that Gray Matter has the bad habit of rejecting legal moves from the opponent, which is an ugly way to win games

Hello Olivier,
In my PC, Dann Corbit, Grey's executable compile, show an error message and exit from Winboard. I have Windows 2000 OS. Maybe the winboard command line needs some extra parameter.
Please you comment.

Hello all. I took a quick look at the code, and this engine doesn't seem to read command line parameters at all.

I've found that this engine crashes with a time control of game in X number of minutes (like a level 0 3 0 type command), but seems to run ok with a time control of x moves in y number of minutes, at least in Arena 1.1. It's probably a divide by zero type bug; I've seen a number of other engines, especially old ones, crash when issued a level command with the first parameter being zero.

As far as not accepting legal moves, it seems to interpret Winboard 2 style usermove commands ok, but it doesn't seem to understand Winboard 1 style move commands (usermove e2e4 is ok, a plain jane e2e4 is verboten).
