[computer-go] Strangest C++ problem yet

[Peter Drake]

I'm working on my GTP interface for tomorrow's tournament. Responses  
to GTP commands go through this function:

void acknowledge(const string message = "") {
	if (commandID >= 0) {
		cout << "=" << commandID << " " << message << endl;
	} else {
		cout << "= " << message << endl;
	}
}

This works fine from the command line and through glGo, but it chokes  
for gogui, Goban, and kgsGtp. Specifically, gogui complains that the  
program never responds to the "name" command.

Now here's the really strange part: if I change that last line to

		cout << "Acknowledging " << message << endl;

it DOES produce output, although of course it's not a proper GTP  
response.

Again, either version behaves as expected on the command line or  
through glGo.

Does anyone have a clue on this one?
