rpc/clnt.h is used by the nismodule so it should be set.
(And IIRC it's used more often in FreeBSD 4.x.)

The problem is that if _POSIX_SOURCE or _POSIX_C_SOURCE is set
__BSD_VISIBLE isn't defined. Because of that certain
functions and defines which Python seems to rely on aren't
defined. Another problem is that some functions like ftello
are defined at a higher POSIX level than python expects.
The cleanest way for FreeBSD to solve this issues for
FreeBSD is to
not define  _POSIX_SOURCE or _POSIX_C_SOURCE. This means
also _XOPEN_SOURCE can't be defined, because then
_POSIX_C_SOURCE
will be defined in cdefs.h.

Can you please explain *why* _THREAD_SAFE is needed for
threaded programs on FreeBSD? Looking at the -CURRENT
sources, I find but a single occurrence of _THREAD_SAFE (in
rpc/clnt.h), which is not relevant to Python.

As for the build problems we talked on python-dev: Can you
please re-iterate what those problems are, if you take the
current Python CVS as a starting point?

The patches contain two parts. A work-around for the FreeBSD
5.0-current
build problems, we talked/talking about at python-dev@.
The second part is the addition of _THREAD_SAFE to the
CFLAGS, if Python is build with threads. _THREAD_SAFE is
needed for threaded programs on FreeBSD.

Can you please list the problems that this patch fixes? They
might be fixed in the current CVS.

In particular, what is the effect of defining _THREAD_SAFE?

In this form, the patch likely won't be accepted. I see it
is not urgent, since the system it applies to has not been
released, yet. So I would like to resolve #635034 first, and
would propose that the _XOPEN_SOURCE issue then integrates
with the framework established there.
