wine log

With wine-5.11 (Staging), Battle.net fails to install either World of Warcraft
or Starcraft II. The installation stops after a couple of GB (when first
installing or right away when trying to to continue the installation) with and
Battle.net showing a popup talking about BLZBNTAGT00000840. When this occurs
the following lines are systematically displayed in the log:

020c:fixme:file:server_ioctl_file Unsupported ioctl 4004747b (device=4004
access=1 func=d1e method=3)
020c:fixme:winsock:server_ioctl_sock Unsupported ioctl 4004747b (device=4004
access=1 func=d1e method=3)
020c:fixme:winsock:WSAIoctl unsupported WS_IOCTL cmd (_IOR('t', 123, 4))

This is 100% reproducible and it also happens in a clean WINEPREFIX. Changing
the Windows version does not appear to have any effect. This is possibly
related to bug #49490.
