Summary: socketmodule inet_ntop built when IPV6 is disabled
Initial Comment:
RTEMS does not support IPV6 and so does not define
ENABLE_IPV6 for Python.
RTEMS contains an aging port of the FreeBSD stack and
the port contains some IPV6 things such as inet_ntop
and inet_pton. This causes HAVE_INET_PTON to be defined
to 1 causing the current socketmodule.c to compile the
socket_inet_ntop code. The assumption being these
functions are only present with IPV6 stacks. This
assumption is valid, how-ever RTEMS breaks this
assuption and fixing this in RTEMS is not pratical.
Removing the HAVE_INET_PTON definition causes
socketmodule.c to compile in a private version. The
private versions have a slightly different prototype to
RTEMS and so the compiler stops with an error.
This patch seems the simplest solutions given it does
not effect other platforms.

I have tested socketmodule.c version 1.268 with RTEMS and it
compiles and works. No further changes are needed.
I added to RTEMS the INET_ADDRSTRLEN define as it was not in
netinet/in.h and the addition took a little longer than
expected.
An RTEMS maintainer raised the point the SUS standard that
defines INET_ADDRSTRLEN is new(ish!) and so Python may not
be as robust on older systems that do not have
INET_ADDRSTRLEN defined.
Thanks for the prompt resolution.

I believe this patch is now superceded by #734231. It
appears that the problem of inet_pton is shared on many
platforms, so the code now wraps the buffer declaration with
ENABLE_IPV6.
Can you please retry the current CVS, and indicate whether
further changes are needed?
