You need to use the sample Makefile template that comes with WinAVR.
Look in the <install>\sample subdirectory. Also, instead you might want
to use the MFile utility that comes with WinAVR. MFile can be used to
generate a Makefile for your project based on some simple input that you
give. The Makefile template that it uses is also the same template that
is included with WinAVR.

FYI: The warning message you are getting is becuase you do not have the
-mmcu=<device> flag in your compiler flags. Using MFile, or the WinAVR
Makefile template, will help you avoid these simple errors.
