The use of a __PRIVATE_DEFINE is highly discouraged.  In sys/features.h
you'll find a comment to that effect.  Python should have used
_BSD_SOURCE but even that is deprecated in favor of _DEFAULT_SOURCE.

No but that doesn't mean the functions do not exist.

The oversight would be the use of the private define instead of the
public one.  If you remove the __BSD_VISIBLE and use _DEFAULT_SOURCE
instead does it help?  If not then there is a deeper issue.
