I've also changed the location of the package source and ran R CMD build mypackage (Rcmd.bat is not working so I assume there is something I'm doing wrong).  However, the warnings are now gone.  The file produced is still a tar (and not tar.gz), but when I look at it within the command prompt windows using dir, it says that the file is a tar.gz.  I don't know what is the meaning of that.

You likely have the Hide extensions options enabled on your Windows system.

Click the Windows start button in the lower left of the display and
enter the words: Folder Options. When the Folder Options screen comes
up on its View tab ensure that that Hide extensions option is turned
off.
