I have a couple more fixes to suggest. In ZeroTTable() in util.c, the 
2 memset lines should be changed to this.

memset(ttable[white],0,(unsigned long)(sizeof(struct hashentry)*
                                      (ttblsize+rehash)));
memset(ttable[black],0,(unsigned long)(sizeof(struct hashentry)*
	                              (ttblsize+rehash)));


In GetGame() in dspcom.c, I would suggest that the hashtable be cleared
with a ZeroTTable() call.  This can be added somewhere very near
the end of the function.  This is necessary especially when running
gnuchess through the test suite as an uncleared hashtable will result in
poor results.
