[tobi@marktplatz tests]$ cat assign.f
      integer*2 i2
      integer*8 i8

      assign 100 to i2
      assign 100 to i8
 100  continue
      end
[tobi@marktplatz tests]$ g77 assign.f

      assign 100 to i8

... so g77 does indeed give an error, which is actually misleading in the
INTEGER*8 case.  So my patch is a definite enhancement over g77 :-)
