The problem I'm seeing (on three different systems) is with Real.toString,
which is printing zeros as 0 or ~0 instead of 0.0.  This seems to be a
problem with Real.class.  To be sure, on my system, I see the following:

[fluet@localhost test]$ cat z.sml

val z = 0.0

val c = Real.class z

datatype t = datatype IEEEReal.float_class
val _ =
  case c of
    ZERO => print "ZERO\n"
  | NAN => print "NAN\n"
  | INF => print "INF\n"
  | NORMAL => print "NORMAL\n"
  | SUBNORMAL => print "SUBNORMAL\n"
[fluet@localhost test]$ mlton.cvs.HEAD -native false z.sml
[fluet@localhost test]$ ./z
NORMAL

Where mlton.cvs.HEAD corresponds to a clean checkout.  Right now, I'm on a
system like:
[fluet@localhost test]$ cat /proc/version
Linux version 2.4.19-16mdksmp (quintela@bi.mandrakesoft.com) (gcc version
3.2 (Mandrake Linux 9.0 3.2-1mdk)) #1 SMP Fri Sep 20 16:08:37 CEST 2002
[fluet@localhost test]$ gcc -v

gcc version 3.2 (Mandrake Linux 9.0 3.2-1mdk)

I'll try to investigate tomorrow; in any event, it seems to be orthogonal
to the Machine.Operand.Runtime changes, so I'll check those in.
