Duplicate UUID is not a warning 2368, it's an error 2270. Could you share a minimal idl you're using to test that?
Calling midl on dlls/oleaut32/tests/test_tlb.idl produces this output: "midl\oleaut32.dll : warning MIDL2368 : error generating type library, ignored : Could not set UUID : nn (0x800288C6)". Adding "midl_pragma warning(disable: 2368)" in file suppress such output.
