ANSI C standard, section 2.1.2.2, says that main may be declared with
zero or two arguments.  Period.

If you write main() with one or three or more arguments, it does not
conform to the standard, and any conforming compiler is free to reject it
as an error.  A conforming compiler MAY allow additional arguments as an
extension, but need not.
