Log message:
    i've spotted a following problem using DBD::Pg under win32. winsock
    functions do not set errno, so some normal conditions are treated as
    fatal errors. e.g. fetching large tuples fails, as at some point recv()
    returns EWOULDBLOCK. here's a patch, which replaces errno with
    WSAGetLastError(). i've tried to to affect non-win32 code.

I thought this was awaiting a merged patch from both submitters?

Certainly I haven't reviewed it, since I thought that we were not
going to apply it until that happened.

The other maintainer said this patch was better.  He wants a few lines
of his patch added as well and he will send that over soon.  You want to
see the applied patch or have it backed out?

Oh, I guess I missed that message.

No, I'll just look at the combined diff once both patches are in.

I have applied both fixes.  Win32 users can start testing.
