Ordinary ocamlopt prints:

  3723
  3723

The cross-compiler prints:

  3722
  3723

The generated assembly is again identical apart from differences which
seem insignificant to me.  Shown below is the diff between the
ocamlopt 3.10.2 for Windows downloaded from caml.inria.fr, and my own
cross-compiler (both running under Wine).

I'm thinking the difference must be somewhere in Wine itself or in the
way that the two compilers initialize the floating point environment,
such as using different rounding modes.

Does anyone have a true Windows version of 3.11.0 that they could
check out the test programs on?

Rich.
