That is understood completely and that is not what I'm asking...
I think that this warning should be printed not just for debug purposes...
So, I'd prefer:

+	if (machid == BI_ARCH_NUMBER_INVALID)
+		printf("Warning: machid not set.\n");

with no #ifdefs.
So, I'm asking is it essential to make it only for debug purposes?
Are there any cases when this code will harm if no #define DEBUG is specified?
