to get it working next release)

exception in the execution of bar, ensure that foo.bar exists.
(Previously, while sys.modules['foo.bar'] would exist, foo.bar would
only be created upon successful execution of bar.  This is
inconvenient; some would say wrong. :-)

so that's another step backwards.

New functions getnameinfo, getaddrinfo. New exceptions socket.gaierror,
socket.herror. Various new constants, in particular AF_INET6 and error
codes and parameters for getaddrinfo.
AF_INET6 support in setipaddr, makesockaddr, getsockaddr, getsockaddrlen,
gethost_common, PySocket_gethostbyaddr.

Added information on the return values of PyArg_ParseTuple() and
PyArg_ParseTupleAndKeywords().

Moved the PyArg_Parse*(), Py_BuildValue() functions to the Utilities
chapter, added a minimal description and reference to the Extending
manual for Py_BuildValue().

Work-around a font-lock bogosity.

Remove unused import.

Some minor cleanups of the code.

Added tests for the roundtrip-safety.

#caused warnings with the VMS C compiler.  (SF bug #442998, in part.)
On a narrow system the current code should never be executed since ch

Marc-Andre: you may end up fixing this a different way, since I
believe you have plans to generate \U for surrogate pairs.  I'll leave
that to you.

Fix showstopper SF bug #442983: use of site.addsitedir() was broken
because it references the global dirs_in_sys_path which is deleted.
The fix avoids deleting that global.
