You certainly can define the main function that way, but the C startup
code generally would expect an integer to be returned, so you should at
least get a warning when trying to compile that (GCC gives one).
Also, it is quite possible to use return in a void function; in this case
it simply exits the function at that point without giving a return value.

It is non-standard in that it is the the main function called by the
startup code to run your program, but other than that, I don't know of
anything really unique about it. Calling main from inside the program has
worked every time I tried it, though I don't think that it is useful to do
so very often.
