AFAIR, Win95b introduced winsock2. Maybe this is the problem. Cygwin uses
3 different ways to get the network interfaces. One for Win95 and Win31,
one for NT and one for Win98, ME, 2k. Maybe the newer versions of Win95
support the win98 interface, but not the old win95 interface. I'll check
this tonight.
This code is in winsup/cygwin/net.c
