In some C environments it's actually legal for main() to return without
a value; there the C compiler will threat this as equivalent to return 0;.
This is not true for gcc on Linux, there main() will return a random
value.
Some C compilers are fairly paranoid and will complain if you don't
properly declare the arguments for main().
Just a few notes by somebody who has been dealing with portability
problems again and again.
