Sorry for the grouchy tone of my last email; I was having a really bad day.

Is this also responsible for why mlton fails to use system()?
This is what's giving me the most grief.

That doesn't seem to work for me. When I install the newer basis library and
try to use the 20041109 compiler, I get a big whack of errors. I didn't
investigate deeper because I assumed that this was not supported.

Using a working cvs compiler between rebuilds does work, and that's what I
used to do. However, I overwrote my working cvs compiler with a broken one
after you commit'd the patch the first time. So, until I build a working,
recent compiler, I can't just do 'make world'.

At least that's my imperfect understanding.

The fact that my only machine with windows, cygwin, and 512MB of RAM keeps
segfaulting while compiling MLton means I need to try about 3 times to get 
a build. Hence the really long build and frustration. =)

Anyways, I will try again once I am by said machine.
I really hope your change fixes system(), as then I won't need to rebuild
the whole thing again for a while.
