Personally, I don't see the point in adding files to the build that
aren't used.  So if an entire file isn't referenced from Wine, I
wouldn't add it in the first place.

If there's a file that is used in Wine, but that has code that isn't
used, you might add it unmodified as one patch, and remove the unused
code in another.  The purpose for adding it unmodified is to make it
easier to diff with the upstream version.

Another approach would be to add the unmodified code, then disable the
unused code using comments or #if 0.  This could be useful if we were
trying to apply patches to upstream to our own codebase.  It seems as
though we update from upstream sources rather seldom, though, so I
don't think this is worth the ugliness of dead code being left in the
source.

A final complication is when one file, which is used, contains
references to files that aren't used.  In this case I'd say add the
file with the references removed, and hopefully the deletions would be
clear in the diff from upstream.

This is all my opinion of course.  What were you thinking?

Well done :)
