You shouldn't need to compile the generated source files, the Mercury
compiler should invoke the target language compiler for you.  (You can
see what it's doing by using the --verbose-commands option.)  If it's
not producing an .exe file (assuming your target language is C), then
something is going wrong somewhere.

What version of Windows and Visual Studio are you using? If it isn't
Visual Studio 2013 and whatever version of Windows was used to build
that package then you are probably going to encounter problems.

By default C, unless you've explicitly told it to compile to Java or C#.

It should already be pointed at one; do mmc --output-cc to see which.
