Include paths are updated to include the directory. It seems that CodeWarrior will search for include files recursively, which means that "error.h" may resolve to the wrong file (there are two). I am unsure of the rules CodeWarrior uses to find header files. Support for older versions of Universal Interfaces has been added. The project code has been reworked after thoroughly reviewing Inside Macintosh: Files. It is not complete, but it compiles, and the behavior of the Save / Save As commands have been thought out more carefully.
