Please note, return values are implementation dependent, and are not defined
anywhere in the LRM.  Making the top-level subprogram a funtion returning an
integer is one solution the compiler writer may choose.  Or it may be included
in a OS isterface package.  I think the POSIX binding do this.

WRT the form of the top-level subprogram, the compiler must at least be able
to handle a procedure with no parameters.  Anything else is at the compiler
writer's discresion.
