I think that there is a regression because in 6.0-rc3 it breaks again (fails to initialize ClientSdk.dll)
Can you please confirm that you are compiling upstream (non-staging) wine with mingw, and if possible perform a regression test?
This should probably also be a new bug report, instead of polluting this existing one.
