> Regular SO options on Windows:

I did not ask about Windows options.  I asked about a feature that is defined in Cygwin yet appears not functional.

> You can abuse Nagle to get similar behaviour cross-platform:

This is not the same thing!

> ENOPROTOOPT (109)... "The option is not supported by the protocol."

Indeed the textual description does not match, and should be changed in Cygwin.  Although, I'm sure it was copied over from Linux, which does not define it properly (probably, historically), either:

#define ENOPROTOOPT     92      /* Protocol not available */

BTW, Windows does that correctly:

WSAENOPROTOOPT (10042) = "Bad protocol option"

Who are you suggesting this to?
