What version of Cygwin are you using?

(Some preliminary poking shows that EAI_SYSTEM is part of the standards that Cygwin should be following, but that at least in 2002 it didn't. *Shame on cygwin*. I haven't verified whether recent versions have fixed that.)

[Derick Eddington (derick-eddington)]

EAI_SYSTEM is from #include <netdb.h> and looking at Cygwin's netdb.h at:

http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/cygwin/include/netdb.h?rev=1.10&content-type=text/x-cvsweb-markup&cvsroot=src

it does have EAI_SYSTEM, but you must not be using that same header. But this doesn't really matter because:

Cygwin does not implement getaddrinfo and so Ikarus implements it's own. So we'll need to make Ikarus's getaddrinfo work with this. Maybe an #if (!HAVE_GETADDRINFO) around that EAI_SYSTEM switch.

[Derick Eddington (derick-eddington)]

That netdb.h I linked to does have getaddrinfo and its changelog mentions it being added two years ago, but http://cygwin.com/cygwin-api/std-notimpl.html includes getaddrinfo in the not implemented list.

I am using the latest, I think rev 1500 still compiled.

[Abdulaziz Ghuloum (aghuloum)]

Added conditional #define for both EAI_SYSTEM and ECANCELED in rev 1509. It was not compiling on my cygwin installation either.
