No. And I'm not convinced that it's worth it, since it would have to emit
the strings you mention below rather than freedce code, so the core of the
compiler would be completely different, and the parser part isn't a big
deal to do with flex and bison.

Do you have any URLs or something where I can get the results of that

Well, it must be compatible with both Winelib and binary emulation. I
think that's all the reasonable requirements it might have. (It might also
be useful if it emitted relay code that could be traced much like

Probably lift midl.exe off the net? I don't think these developers try to
create their own COM objects, though, so they don't need an IDL compiler.
You don't need MIDL to use other people's COM objects.
