->The expression is of this form:

->	a ? b : c = d;

->The illegal lvalue is:

->	a ? b : c

->(sic)!  The `?:' operator has a higher priority than the various assignment
->operators.  The following does what was intended:

->	a ? b : (c = d);

What really was intended is

        *buf -= mfag ? mean.median : Mfalg ? mean.mode : mean.mean ;
        buf += 3 ;

( Or did I get this wrong, and the original does NOT increment tree times ? )
