Well, 9.1 currently has:
errmsg_internal("failed to enumerate network events: %i", (int) GetLastError()))
Prior to your patch, master had:
errmsg_internal("failed to enumerate network events: error code %lu",
GetLastError())
And you changed it to:
elog(ERROR, "failed to enumerate network events: error code %u",
WSAGetLastError())
So obviously there's a conflict there. In the previously-posted
version, I chose to just take your version, but I'm not sure whether
it would be better -- in the back branches -- to simply replace
GetLastError() with WSAGetLastError() and leave it alone otherwise.

Well, this thread started as a bug report against 8.3.7...
