Thanks!

A big request:

could you make a Fruit 2.1 Windows compile for me that prints the real time and the user time? I don't manage to compile it with gcc in -mno-cygwin mode, it produces tons of error messages. (On Linux it compiled fine, and cpu_now() and real_now() also worked with good precision.) What I need is a version that prints

Code:
 startTime = WallClockTime(); // time stamp (millisec)
cpuTime = CPUtime(); // Total CPU used upto now (millisec)
printf("info string times @ %u\n", startTime);


immediately after it receives a "go" command (this code is in protocol.cpp), and

Code:
stopTime = WallClockTime(); // time stamp
cpuTime = CPUtime() - cpuTime; // Consumed CPU time
printf("info string times @ %u: real=%u cpu=%u\n", stopTime, stopTime - startTime, cpuTime);


just before it sends "bestmove". (Also in protocol.cpp.)

I have written a small program that extracts such messages from the debug file, and calculates from them the delay between sending a move and the opponent receiving it, and CPU time stolen by the GUI.
