I was planning on adding COM_NO_WINDOWS_H explicitly to all source
files in the dlls folder that require it. Once this is complete, the
widl code generator can then be updated to support this behaviour
(otherwise the widl change will break the Wine build).

This will also prevent the "symbol already defined" warning on the
files that already define this when building with midl generated files
using the VC compiler.
