We track all our binaries so each commit is a working state of our system. 
Git just seems to know they are binaries and reports them as such in the 
diff pane of gitk:  "Binary files a/path/binaryA and b/path/binaryA differ". 
We are currently using 1.7.1.  I guess it "knows" they are binaries because 
we don't their paths in the "gitattributes" file.

Based on the gitattributes manpage, it sounds like you have "diff" set for 
the path to your binary listed in your .git/info/attributes (git attributes) 
file.  If the binary is in the same path as the source you could set the 
"binary" attribute macro for your binary(s) if the path or name is 
distinguishable from the source.  I played around with this in the past, but 
currently don't have a need for it in my current configuration, so I'm 
getting all of this from the gitattributes manpage, 
http://www.kernel.org/pub/software/scm/git/docs/v1.7.1.2/gitattributes.html.
