Does anyone know of a way to pick up the netmask and broadcast mask
of an IP interface under SunOS3.5? I need to emulate the facility
provided by SIOCGIFNETMASK and SIOCGIFBRDADDR under 4.3.

The only differences from 4.3 that I'm aware of are that ifreq.ifr_broadaddr doesn't exist (you get the broadcast address from ifreq.ifr_addr instead) and that the netmask returned by the other request can sometimes be 0.0.0.0 when subnetting isn't being done.
