I have a WIP CI run on my fork for Windows using Cygwin (it a bit ugly
right now), but it has a fair amount of sim builds failing. Could someone
take a look. I'll put a draft PR up tonight for CI but for now this is what
I have.

It also times out, but that can be dealt with later.
Most of these are failures related to networking with the simulator
under Windows with wpcap. That networking logic is very different under
Windows than Linux where a tap driver is used. That logic has not been
used in a decade AFAIK and I am not sure if it ever worked. I believe
that these are real errors, but probably not fixable in the short term.
I think we cannot test simulator-based network under windows right now.
I vaguely recall someone telling that they had networking with wpcap
working a decade or so ago, but I have heard of no used since them. It
probably should be marked EXPERIMENTAL.
sim/module:
This looks like a conflict between Cygwin header files and w32api headers
/usr/include/cygwin/socket.h:27:8: error: redefinition of 'struct
sockaddr'
27 | struct sockaddr {
/usr/include/w32api/psdk_inc/_ip_types.h:70:8: note: originally
defined here
70 | struct sockaddr {
Similarly with struct linger, the prototype of socket functions, and
probably other things. My only conclusion is that wpcap is not
compatible with Cygwin? This may not be something we are able to fix,
or perhaps it is something that could be fixed as simply as removing
some includes from up_wpcap.c?
sim/nettest: Same issues
sim/tcpblaster: Same issues
Everything else looks fine.
