-- Make win32.c compile under Cygwin. It's just one function (fullpath()) that
-  needs to be replaced.
+
+- update the Makefile so that Cygwin can generate a DLL. The entire codebase
+  compiles under Cygwin otherwise.
 - Hmm...we can determine the actual CD-ROM drives under Win32, but how do you
   decide that there's no disc in the drive?
+- MacOS support.
+- Move the integer types to something abstract. uint32, etc.
+- Ditch the "standard" i/o routines (fopen() and friends) and move this into
+  the platform drivers.
