CodeVisionAVR 
http://www.hpinfotech.ro/html/download.htm
has support for the DS1307.
The Evaluation copy has a 2kbytes code size limitation. I believe that is the only differance between that and the commercial version. Oh, there is no support. Support is available on the Yahoo "CodeVisionAVR" discussion group.

One of the best features of cvAVR is the CodeWizard. With it you can tell the compiler what micro you are using, how you will be using the ports, in/out things like that, timers, an LCD and cvAVR will setup the code to initilize most, if not all, of the micro. If you select that the DS1307 will be used with it and give the port number cvAVR will setup the init code. There probably is a code included to take your DS1307 for a test drive. How would that be?
