In that case we should use __func__.
But we discussed this at some length 3-4 years ago and decided to use __FUNCTION__. I don't remember why. Perhaps problems with gcc support for __func__?
(It could have been that compile-time string concatenation was involved:
printf("xxx" __FILE__); /* works */ printf("xxx" __FUNCTION__); /* doesn't */ Or not.)
