Fix #2919 by removing the entire block.

This code represents only risk and does nothing useful for anything
that can compile fish.

In C++ situations where __STDC_VERSION__ is unset (as it should be),
fish was assuming we are on < C99 and setting it to __FUNCTION__.

Basically always, __PRETTY_FUNCTION__ ends up reaplaced by __FUNCTION__, this hurt
error message usefulness and richness.

__PRETTY_FUNCTION__: const thing::sub(int)
__FUNCTION__: sub
