On systems that support nameless unions, which I have no doubt is the 
case of the testbot's build environment, my patch does not changed the 
preprocessed code. So I don't think it's the cause of these errors.

However what is strange is that the testbot's VMs that run the tests for 
test.winehq.org don't fail. In fact they skip the quartz tests entirely 
which seems to indicate a different VM configuration is used.
