[Python-Dev] Problems with socketmodule (getnameinfo & getaddrinfo)

That should be fixed now. stddef.h is included in socketmodule.c; if
it is not available or does not define offsetof, an additional
definition is provided.

I don't know how to solve this one. If distutils builds the modules,
makefile dependencies won't help.

I took the simplest solution that I could think of, delegating
inet_{pton,ntop} to inet_{ntoa,addr} for AF_INET, failing for all
other address families (AF_INET6 in particular). I've verified that
this code does the same as the builtin functions on my Linux system;
please let me know whether it compiles for you.
