The ANSI C standard defines a hosted environment and a freestanding
environment. Several things are relaxed in a freestanding environment,
including what library functions are available, what type main returns,
what args it takes, and even whether the function called at program
startup is named "main".
I think that the Right Thing would be to add a -ffreestanding flag to
gcc/egcs, and have that flag turn off the type checking on main(). When
the -ffreestanding option is not used, main() should be typechecked.
