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 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.
