I meant v4-mapped IPv6 addresses, not sure the inverse exists ;) You get
different behaviour on different platforms w.r.t. attempts to bind to
::/port and 0.0.0.0/port for a given port, depending on whether
v4-mapped IPv6 addresses are supported, and which order you attempt the
binds, etc. For a test app it's probably sufficient to simply ignore
bind() errors and hope for the best.
