You are right that playing gnuchess against itself does not *prove*
that gnuchess is working.  However, Tom McConnell (who sent that mail)
was able to reproduce the incorrect "illegal move" messages with this
test when he used some combinations of compiler flags and not when he
used others.  Also, I'm sure that Tom continued to use gnuchess after
apparently getting it to work; having it play against itself wasn't
the only thing he tried.

Therefore, I think you should still try the compiler options Tom
posted.  I don't have any knowledge beyond his, as I don't have access
to an RS6000.  I don't think Mike or Stuart do either.

To refresh your memory, here is what Tom said:

Note that Kong Sian was NOT using gcc.  You have to fix a small bug in
gnuchess.h to compile gnuchess without gcc.  Use the following patch:

iff -c gnuchess.h.~1~ gnuchess.h 
*** gnuchess.h.~1~      Tue Jun 22 06:49:33 1993
--- gnuchess.h  Wed Sep 15 11:22:27 1993
