Well... More or less. In fact, it doesn't compile out of the box,
because of EWOULDBLOCK that doesn't exist as such on Windows.

Even worse, testing errno in such a case is a non-sense, since socket
errors are reported via WSAGetLastError(), which has nothing to do
with libc errors (that's what errno really reports). Using E*
constants is broken as well, since socket errors are really WSAE*

The included patch does the first half of the job (using correct
values for E* constants). It just helps compiling, and does not fix
anything. The second part is to change all reference to errno in a
socket context to something that returns errno on Unix and
WSAGetLastError() on Windows.

Suspects are alarm.c, auth-pword-client.c, data_link.c, events.c,
session.c and sp.c. sp.c is quite nasty, since it *affects* errno
(lines 202 and 209, "errno = ERR_TIMEDOUT").

And don't forget you'll never get a dog to walk upright
Just 'cause you've got the power, that don't mean you've got the right.
