Funny place. Usually it's the other way around in mission-critical 
networks. I know the swedish military are forbidden by law to use 
anything but NetBSD in most of their networks. Windows' IP-stack is just 
too shoddy to be used in really critical places, even if they made a 
near-complete ripoff from OpenBSD when they released Win2K (it seems 
they screwed up enough of it to make it malfunction anyway).

The nagios plugins lean heavily on certain system applications usually 
only found on unix systems. I don't think a cygwin port is currently 
planned and I seriously doubt if you will have any luck in making many 
of them run.

check_icmp (as included in the dist) won't compile under CYGWIN unless 
you have BSD-compatible headers installed (which you apparently don't).
If it weren't for the initial "struct icmp" warnings (which later causes 
the errors of "dereferencing pointer to incomplete type") I would 
recommend you download the latest check_icmp plugin (although it 
wouldn't work under XP SP2 anyway, due to imbecile (and easily bypassed) 
socket restrictions).

The best option you have is probably to run make -i (continue on errors) 
and take whatever plugins happen to build. You'll be running a severely 
crippled install, but in a windows-only environment I assume the 
IT-staff are used to a certain degree of wobbliness anyway.
