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.)
