Good -- I switched back to Cygwin to try to see what the "right" answers 
were.  When I saw they didn't work, I got nervous I had accidentally 
broken something in the common code.  That's a relief! :-)

Actually, the file path thing turns out to be a problem.  Undisciplined 
as always, I decided to try building MLton to see what would happen.  
The resulting binary actually runs, but when it starts trying to build 
the basis library it dies with a Path exception.

I made some changes to try to handle DOS-style paths, and rebuilt the 
Cygwin compiler.  I'll probably try the Mingwin version again tomorrow.

I'll check it.   One thing I noticed is the Windows library produces 
dates with a leading zero, so "Jul  4 2004" displays as "Jul 04 2004", 
which might be part of the problem.

Anyway, I'll play with the other stuff tomorrow and see where I get.
