windowscodecs: Fix build failure on OSX.

[Sebastian Lackner]

The build failure unfortunately was introduced by my last patch
http://source.winehq.org/git/wine.git/commit/863f432a7d73b8b480a742fcbaf01de33964cc21

Somehow I missed that this part is OSX specific and tested on Linux only - sorry for
the trouble. :/ The patch was tested by jam__ on IRC, would be nice if someone could
double check that no other warnings were introduced by my original commit.
