Any time a new version comes out, you just have a new orig.tar.gz, and
you modify the changelog accordingly. There's no problem having
multiple orig.tar.gz's laying about so long as you've got the right
upstream versions in your debian/changelog.

Right, but the way I'd recommend that you do this instead is using the
following:

0.9.9-00winehq~breezy0 and 0.9.9-00winehq~dapper0 et al. [+ or . will
also work, but ~ is probably best.]

The problem is that you're forcing the packages in a major upgrade to
Pre-Depend upon an upgraded version of your package instead of
allowing the upgrade to just happen automatically. Of course, the
rpaths which are actually in the library are $ORIGIN/.. which are
moderately more sane than the usual rpath that libraries carry around
(which often is tied to the directory in which the library was
actually built.]

There's been quite a bit of change in the package from pre 0.9.9 to
0.9.11; in general fixing the bugs is part of what it means to release
a version of upstream packages to distributions.

For example, you don't include desktop icons, entries into mime info
for ms dos programs, etc.

For example:

Package: libicu34-dev
[...]
Replaces: libicu21-dev, libicu28-dev, icu-data, icu-i18ndata
Provides: libicu-dev
Depends: libicu34 (= 3.4.1a-1), libc6-dev | libc-dev
Suggests: icu-doc
Conflicts: libicu21-dev, libicu28-dev, libicu-dev, icu-data, icu-i18ndata

This means that you should have a Build-Depends line that looks
something like:

Build-Depends: libicu34-dev | libicu28-dev | libicu-dev

When libicu is upgraded to libicu35 (or whatever), your package can be
rebuilt against libicu35 with a trivial binNMU instead of requiring
uploads of the package.

NP; I started in because I was interested in seeing if you had made
changes that should be brought to the Debian maintainer's attention;
but having started, I thought you should be aware of what you need to
change if you want upgraded packages in Debian. [Which is probably
very similar to the changes required of packages in Ubuntu.]

[You'll note too that your libwine and libwine-dev packages are
totally empty... if that's intentional, then they should probably just
be Provides of the wine package.]
