I forgot to mention: with this change, we now correctly generate
text files in DOS/Windows format, rather than Unix format.

This means that if you want to run the test suite for the `il' or `ilc'
grades, you should make sure you have a version of the test suite which
is in DOS format (in particular the `.exp*' files need to be in DOS format).
If you're using Cygwin, this can be obtained by checking out the test suite
in a directory which is mounted in text mode
(which you can get via e.g. `mount --text C: /text').

(The source code also has some support for opening files in Unix format,
by setting ML_default_file_encoding to ML_Unix_file_format rather than
ML_OS_file_format.  But currently this is not used.)
