While getting the code up to C99 standard, IntelliSense as become much more useful. I can now see all the functions is the solution explorer and flip back to function declarations with ease. I decided while I was doing this, I should get rid of some of those 600 some-odd warnings that have been hanging around. This required me to start writing prototypes so that those undefined declarations can get cleared out. I imported the obsolete proto.h file and started to update all the prototypes in it.
I didn't work on the builders as the refactoring took priority. It wasn't a lost day as these are all things that need to get done.
