These instructions recommend building v19.06, and patching to enable
shared library builds. This will allow users to substitute a build of
libportaudio-2.dll with ASIO support if required. We cannot
redistribute binaries with proprietary, closed sources, like the
Steinberg ASIO SDK, although users can build it themselves for
personal use.
A separate install of the portaudio library is now required, see
"doc/building on MS Windows.txt" for a suitable recipe.
The map65 code base is still MS Windows specific in some areas so
don't expect successful builds on Linux or macOS yet.
