The Windows port is progressing but is still work in progress. We
currently have a clean compile and have been able to compare the gcc and
the MSVC performance (as indicated in a previous mail). As you can see, we
have 

	VC/gcc-asm_fast is ~ 1.3
        VC/gcc-none is ~ 0.9

We are still struggling with the bootstrap of the compiler : problems with
the scripts and portability problems with the standard Mercury library.

DLL are not supported in the current Cygnus Mercury environment. Fergus
has worked on that. We are working on DLL support in our MSVC port.

As soon as we have a reasonable release and packaging, we'll let the
Mercury community know (it could still take some time because we want to
have COM client support).

The support of threads and a ruggedized COM server suppport is, of course,
on our list of tasks, but is not for the next few weeks :-(
