Oh, there is one more possible synonym to enigne and machine: Chess 
program which is used in these strings:

Starting chess program
Can't have a match with no chess programs
Illegal move "%s" (rejected by %s chess program)
Failed to start %s chess program %s on %s: %s\n
Illegal hint move "%s" from %s chess program
Waiting for first chess program
Waiting for second chess program
Starting %s chess program
Error writing to %s chess program
%s program exits in draw position (%s)
Error: %s chess program (%s) exited unexpectedly
Error reading from %s chess program (%s)
Error writing to chess program

So what is the difference between engine, machine and chess program? And 
if there is none, shouldn't the same word be used in all places?
