Who is going to access this DLL?  Another mercury program or a program
written in C/C++?

The build system under windows doesn't currently allow one to create a
library which is exported as a DLL that can be consumed from another
mercury program.

If you want to create a DLL which is accessible from C this is possible though.

Add the :- pragma foreign_export(c, ...) declarations to your code.

Build you code as a library (you get a static library).

Write an interface in C which has the correct DLL declarations for a
set of functions and each function definition just calls the mercury
foreign exported function.

Then link the resulting object file and the static library together to
create a DLL.
