Hello all,

winsock.h does provide
struct sockaddr
struct sockaddr_in
so that should not be the problem.

I think the way to eventually go will be back to what I had
before - a union of sockaddr, sockaddr_in, and maybe sockaddr_in6.
After all that does not cause any portability problems at all
(it is a plain C union :-)
But please let me repeat: unless there should be a majority of the
Siemens M3UA developers supporting that change, I will not do so
until after the the SCTP and M3UA bakeoffs.
Best regards,
Andreas Jungmaier
