From: Nikolay Sivov nsivov@codeweavers.com
The issue comes from per-field structure copy that we generate on 32-bit. For non-pointer fields like "const int" this breaks compilation when assigning to a const field. The best solution would be to remove local struct variable completely and pass first argument address as a stack address. This is what midl does. My understanding is that doing it midl way used to break on some compilers, and we have to keep the copy. Once we encounter pointer type that needs such copy, we'll have to patch it more to cast the const away for example.
Such type modification matches what midl does for structures in _Thunk's, so the fix itself is correct.
