#compile options for gnuchess
#    Search options
# -DHISTORY use history killer hueristic 
# -DKILLT use killt killer hueristic 
# -DNULLMOVE include null move heuristic
# -DDEEPNULL include deepnull move heuristic
# -DUNLIMITEDCAPS allow unlimited depth captures
# -DPRUNE enable marginal forward pruning
# -DNOMATERIAL don't call it a draw when no pawns and both sides < rook
# -DNODYNALPHA don't dynamically adjust alpha
# -DOLDTIME use old ply time estimating function
# -DLEGAL generate only legal moves instead of psuedo-legal
# -DCACHE  Cache static evaluations 
# -DNODITHER no random element to evaluations
#
#    Verbosity options
# -DBAREBONES compile for max speed no statictics etc kept
# -DQUIETBACKGROUND don't print post information in background ( easy OFF)
# -DHASHSTATS keep hash table statistics
# -DMORESTATS print more hash table stats
# -DQUIETBOOKGEN Don't print errors while loading a book or generating a binbook
# -DSEMIQUIETBOOKGEN Print less verbose errors while reading book or generating binbook
#
#    Miscellaneous options
# -DHAVE_TIME_H have <time.h> header
# -DHASSTRTOUL if your machine supports strtoul() else strtol()
# -DHASGETTIMEOFDAY use gettimeofday for more accurate timing
# -DNOMEMSET if your machine does not support memset
# -DECO if you want support for eco database
# -DCLIENT create client version for use with ICS
# -DLONG64 if you have 64bit longs
