[MLton] Experimental 64Bit

[Ray]

I see the same floating point exception on a FC 5, dual AMD64.

I have been compiling along on the 64 bit branch without a problem I'd
say within the last 3-4 weeks.  When I saw the announcement I did an
update which appeared to be only a modest 10 files or so.  The make
segfaulted on xmlShrink (if I recall).

The binary build from Experimental has the immediate floating point
exception.

Let me know if I can be of further help on further tests.
