I'm having a hard time understanding the motivation behind this warning, because I've never encountered a place where it would have helped find a problem. On the other hand, I've seen a number of macros that wrap functions (with the same name) that benefit from the suppression of recursive macro instantiations, and those would come up as false positives with this warning.
