I am building a fairly large application using MS Fortran 5.00.
For no apparent reason, I am getting message M6111, "floating-point
error: stack underflow" in my code.  Worse, apparently random
changes make the error go away:  things like changing by 1 the
initial guess fed to a nonlinear least squares fitting routine.
(The parameter in question is the center position of a Gaussian
which is several wide in the units I'm using.)

A while back, I complained about this to Microsoft, and they sent
me a new 87.lib for MS Fortran 4.1 and MS C 5.1.  Should I use this
with MS Fortran 5.0 as well?  I really don't feel like debugging
Microsoft's compiler for them.
