 While this whole code drop can likely just be dropped nowadays, since we
 default to C99 in the base system, the PR is invalid as the behavior is
 entirely within the limits of an implementation. C89 doesn't contain
 __func__, so code making assumptions about it is wrong to depend on the
 implementation namespace. C++ before C++11 doesn't contain __func__, but
 gets __PRETTY_FUNCTION__, which is quite reasonable. C++11 itself
 doesn't specify what __func__ should give, so again __PRETTY_FUNCTION__
 is quite fine.
