more illegal code in g77 testsuite

[Steven G. Kargl]

980519-2.f contains illegal Fortran; yet g77 compiles
it without a warning or an error.  A cut-down version 
of 980519-2.f is

      subroutine simul_trace(in, Xsp)

      common /Idim/ jT_f, hd_T, jT_l
      
      real Xsp
      real in(jT_f-hd_T:jT_l)
      
      in(jT_f-hd_T) = Xsp
      end

The expression jT_f-hd_T is illegal because
hd_T is a real variable.
