I think that this error is unrelated to MLton and indicates a
problem with your Cygwin setup.  There are lots of messages on the
Cygwin mailing list about the "I have no name" problem.  Here are a
couple.

Aha.  I believe that this explains the sread problem.  MLton was
opening a binary file (world.mlton) in the default mode, which on my
machine happens to be binary (binmode) and on yours happens to be text
textmode.  I have patched MLton to always use binary mode and the fix
will go out in the next release.  In the meantime you can add binmode
to your CYGWIN environment variable with the following line in your
cygwin.bat file.

set CYGWIN=binmode

Hopefully with the combination of this fix, and your fixing the "I
have no name" problem based on the above links, MLton will run
successfully.  Let us know how it turns out.
