   So in other words, the copyright on the DLL should read: (C) 200X
   Auth#1, 200Y Auth#2?

Yes, with the GNU GPL after that/those lines.

   I probably could have stood to have been slightly more specific,
   Although the app links dynamically to the DLL, the app itself is
   largely just an interface to the object wrappers (also created by
   author #2) in the library.

   Example: Calculator (say) app written by author #1. Author #2
   scraps author #1's interface, adds a few minor features, creates
   object wrappers, coverts the app into a DLL, and builds a new
   interface that links to the library at run time.

   To me it doesn't seems 100% kosher for author #1 to lose the
   copyright on the bundled app as the application engine is his work.

He doesn't loose anything, author #2 modified an pre-existing work
which was copyrighted.  So author #2 most follow whatever license that
work was licensed under, in this case it was the GNU GPL, so section 2
applies.  Please read this section, it isn't very hard to understand
if you take a few seconds of your time.
