Doesn't the above essentially say we can't distribute this?
I'd say it gives no indication either way. The existing twain.h in our source tree is the same. Looks like this is the actual license: http://www.twain.org/twain-license/ Not sure if that lets us use it or not. The official 2.x DSM is LGPL licensed and hosted at https://github.com/twain/twain-dsm. It includes twain.h in its source tree. (How do I know that DSM is official? The twain.org website under "Specification" links to a project on sourceforge that links to that. And it's mentioned in the PDF spec, which says to obtain the Windows DSM from twain.org. Is that sufficient documentation for our purposes? I don't know.)

It may be a good idea to add this to the file header. But I must confess that I don't see why you need another copy of that file, instead of simply adding the missing definitions. -- Alexandre Julliard julliard(a)winehq.org
It seemed cleaner to me to do it with a separate header, because it enforces the requirement that our builtin DSM is 1.x and uses no 2.x features. But I can do it the other way if you prefer.

Yes, I don't think that duplicating the header is making anything cleaner. -- Alexandre Julliard julliard(a)winehq.org

It may be moot at this point, but for what it's worth, it doesn't have to. The default is always that we can't distribute things, a license needs to give us permission to allow that. I.e., code without any explicit license wouldn't be distributable by us.
