- Shared_malloc returns NULL on failure
- Sync changes
- Unfsck 4->8 indenting change
+- Use 2 seperate u16 values for throttle rate in/out
+- Defer adding radius fds to the select loop until become_master
* Thu Sep 02 2004 David Parrish <david@dparrish.com> 2.0.2
- Combined LCP patches from Iain and Yuri. This should allow Windows 2k/XP
