As Alexandre implied in
http://www.winehq.org/pipermail/wine-devel/2009-January/071769.html
one should not fix these warnings casually.
A real fix probably involves actually handing
the error rather than printing a warning.

The last thing we need is an army of people
papering over compiler warnings.
