Can someone can confirm me OLE/ activeX control can't be compiled using clang but only with MSVS ?

MIDL-compiler needed - for microsoft interface definition language (IDL) files... and it exists only in MSVC, as I understand... nothing changed...
I remember in Borland was easy way to build COMdll - also with ATL - but it was too long since now... and Borland also had its own compiler...
ATL as for smaller projects than MFC, but still resembles MFC, -- are both of rather complicated structure... and it is more difficult to create COM without ATL (rus here example & limitations)...
though really I still don't understand ? Why

OCX seems to be sort of out of fashion anyway.

- because, AFAIK, all libs in Windows are still interacting with each other like COM-objects... Cool

perhaps the reason is just the fashion for NET and thus its "COM Interop" possibilities for managed-and-unmanaged code interaction...
but still only Microsoft gives Active Template Library (ATL) & MIDL-compiler Sad

And, anyway

Also, about MSVS : template <>
inline unsigned GetHashValue(const Guid& guid) { return GetHashValue(~guid); }

I'm just not sure that modern compilers are still very friendly with "inline" (just have read somewhere this - do not remember the source)- perhaps it's worth to refactor this piece of code without "inline"?
p.s.
sorry for my late viewpoint, but still I'm really having some interest in this topic... even in U++... if I will make smth to work (not sure) - of course will publish... in spare time

Best regards.
