I reran the dpara check under OS/2 2.0 on my machine with those flags
-FPi87 -G2 -AL -Od, and surprise surprise, MS Fortran 5.1 came out
with only one SERIOUS DEFECT (after milestone 160), and completed the
test.

But, BTW, for 1./0., the answer was, as before, 1.  And interestingly,
Paranoia did not flag that as being a problem.

(Dov: I could uuencode my dpara.exe and e-mail it to you.  That would
let us establish whether the difference we note is between 5.0 and
5.1 or between your and my machine.)
