I see. And the system does have inetpton? That sounds like a bug to me - there should be no inetpton if the IPv6 API is unsupported. Agreed. I will disable them.

I disabled HAVE_INET_PTON in the pyconfig.h although the functions are present in the RTEMS header files as suggested. This throws up another error. When disabled the inet_pton and inet_ntop funtions in socketmodule.c are built. The RTEMS prototypes and the ones provided in socketmodule.c are not extactly the same giving a compile time error.

The RTEMS history is the IP stack is a port of the FreeBSD stack from a while ago. It must have some IPV6 things how-ever as far as I know is not working on RTEMS. I suspect it is not complete/current.

I feel the best solution is to define HAVE_INET_PTON in pyconfig.h.

So I think the configure test should be changed to define HAVEPTON only if all prerequisites of its usage are met (or the entire function should be hidden if IPv6 is disabled). It would make Python more robust, but this is a mistake on my part.

I wrapped 'socket_inet_pton' and friend with ENABLE_IPV6 and sockets under RTEMS work.
