I see two cases here:

Case 1:  You intend to upload this package to CRAN

         --> Don't include the dll in the first place. See 'Writing R
             Extensions' for details.

Case 2:  You only plan to do use this locally.

         --> Learn more about package builds. See 'Writing R Extensions' for
             details, as well as 'R CMD INSTALL --help' and pay attention to
             single architecture builds.

             The Visual Studio tool chain is not officially supported by R,
             so you are unlikely to get specific help. You mix this, but it 
             is an advanced topic, and it is somewhat outside the supported
             range of endeavours with R, you are on your own.

             Google for 'mixing MinGW gcc and Visual Studio' and other topics.

Good luck,  Dirk
