Well --

    Having read the letter from Chris Siebenmann about how Unix normally
    ignores a return value if one is not supplied, I still has a problem.

    Isn't it the same thing to want to return a "all ok" signal to the
    operating system if no other value is supplied (ie. exit(-1);).
    I assume that Unix does return "some kind" of value if one is not
    supplied.  This is what VMS is expecting.  If you don't exit in a
    particular way (ie. exit(-1);) then VAX C assumes everything went ok,
    puts a 1 in r0 and returns.

    Where should the code be modified to cause a return from main to be
    different from a return from any other routine, in that a assumed
    return value of 1 is supplied in r0.
