Thinking about it I think it is a problem similiar to 64-bit file
support: CygWin DLL uses the 64-bit structures also on Win98, with no
problem, isn't it? (but of course the OS doesn't support them)

IPv6 support could be on a similiar base: the DLL "always" supporting it
and silently returning error when the OS doesn't have that support (I
guess detection could be as easy as not finding the wship6.dll dinamic
library).

Problem is: do applications behave correctly when they try to listen on,
maybe 0::1 and the network layers says "nay"?
I guess they should, at least...
