Still gotta work on this, sorry!

For the impatient/desperate: This was built with Visual Studio 2005 on
Windows XP. For the libXMP parts, I used an old version of CMake (3.12?)
with a command line like the following:

    cmake -DCMAKE_BUILD_TYPE=<Debug|Release> -DBUILD_SHARED=OFF
    -DLIBXMP_CFLAGS=</MTd|/MT> -G "NMake Makefiles" <...>

The official release is built with Release_ANSI for maximum
compatibility.
