Finally!

I suppose the lack of comments on my program is because you
don't have allegro.

Well, a compiled verision is available at my site. (link under sig)

#1: My C++ compiler (MSVS6) stopped working a while ago.

#2: Allegro needs a dynamic link library ALLEG40.DLL to be able to run EXEs that are using Allegro

Well google can solve #2 quite easily ^_^

I downloaded the DLL, but it doesn't seem to work. The screen just stays black for a moment, then the program exits... :???:

It ain't needed. If you realize, every IDE that works with C or C++ does not have a special colour for functions, not even the most common. That has to do with the way C/C++ is designed as a language, as Neo said.

Nevertheless, it *is* requested by some people...

[Neo]

In Visual C++, only the keywords (the list I printed above) and numbers have a color, and of course special signs like { }, ( ) and [ ].

Could you search the text for "(" and highlight/bold the letters before it, stopping at whitespace? That would find functions and some keywords (with some tweaking to get the times where the function name and parenthesis w/ arguments are separated by a space.)
ex:
printf ("Sup");
