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.)
