I wish Apple would have an additional #define too, but they don't.

The other option sounds bad.  On the first minor kernel update, Python 
won't compile any more.  In the manner I applied the patch, a minor kernel 
update will not break anything.  When they fix the headers, we can fix 
Python's configure on our own schedule, since this patch won't regress 
with fixed headers.
