ok

The only OS i see that uses OSIOCGIFCONF was AIX and it was mandatory in 
order to make it work like the other unix with the `normal' struct ifconf.
So an #ifdef OSIOCGIFCONF should be ok (since it should be declared in the
same include file as SIOCGIFCONF). An #ifdef __aix is harder to handle 
since it depends on the compiler. Otherwise a configure option like 
HAVE_AIX or HAVE_OSIOCGIFCONF is ok also.
