Thanks for chasing this down.  As you probably know, each import of
Heimdal takes multiple days to complete at test, even just to get it
working on Linux, let alone other hosts.  It's difficult to also address
portability across all our other hosts at the same time, and even more
difficult to pin-point what part of the import has caused the issue,
which is why I've been unable to jump on this issue in the timeframe you
had hoped. 

Anyway, as regards this particular issue, I suspect this may be another
problem cased by the way we include "system/network.h" in our
heimdal_build/roken.h replacement (which then includes

That's needed to ensure we do socket_wrapper correctly in the Samba
build system, but has exposed similar header ordering challenges like
