One minor point (which you should feel free to ignore, since I'm not an
active code contributor): If you instead write a function definition as:

    main(int argc, char *argv[])

with a newline before the function name, then you have the nice property

    grep ^main *

will show you the definition of any given function without having to
search through all the uses of the function.

Of course, any IDE or tags system will let you do this more easily and
without regard for formatting, but when I'm hacking on code or
investigating some problem, I frequently find that poking about with a
pager, grep, and a UNIX shell is faster than diving into an IDE, so these
sorts of neat tricks can be quite helpful.
