MIDL generates enum typedefs without a prior type declaration, as well
as using explicit enum underlying type specifier. None of this is
supported in MinGW.

AFAIK the patch has been requested and used by MinGW users to fix their
WinRT generated headers with C++ code.
This does the following kind of changes to the headers:
