I don't know anything about the particular issue you're working on, so
I can just speak generally.

We try to avoid creating internal, Wine-only APIs. Sometimes it's
necessary, and when we do that, the header goes in <include/wine/>.
One example is "gdi_driver.h" which defines the interface between e.g.
user32 and the graphics drivers.

Are the structures you need declared publicly in the win32 API, even
as opaque pointers? If so, they may belong in <include/winternl.h>.

A specific proposal about what changes you'd like might bring more
detailed responses.

Hope that was at least a little helpful,
