#  one of the two following definitions for "objects" should be used.  The
#  default is to compile everything separately.  However, if you use the 
#  definition that refers to crafty.o, that will compile using the file crafty.c
#  which #includes every source file into one large glob.  This gives the
#  compiler max opportunity to inline functions as appropriate.  You should try
#  compiling both ways to see which way produces the fastest code.
