Well, this must not have any effect.  If it does something is broken.

No, since this is wrong.

This never must happen since the files have hopefully the same name.

Well, if there are difference use

	sysdeps/generic/bits/stropts.h

as a basis and modify constant values and definitions.

Yes, stubs which return errors.

If this does not involve much code than it's ok.  Also, this
implementation then must be th *only* STREAMS implementation.
