Keep in mind that I'm a dirty, rotten cheater. I created a source file which #includes all of the original source files. I told the compiler to inline whenever it felt like it. With a tiny source code like this, that tends to be a very good idea. I also targeted the P6 chip instruction set, which gives a big boost. Similar options with other compilers may give similar results. OTOH, the Microsoft compiler does emit great binaries. You might try to recompile with maximum optimization, but give it TSCP.C instead of the separate source files. I bet your compiler will nudge closer to the better mark.
