 I think those might indicate problems in Wine and not lmi or wxMSW. Both
functions mentioned above are supposed to only return 0 if they fail and
they must be setting last error in this case, so they're definitely not
following the documented postconditions.

 As usual, I could probably look into Wine sources and confirm this and,
maybe, even provide a fix. Please let me know if I should do it.
