I think we need to fix SYS:RUN-PROGAM under Windows, file this as an
active bug in Trac, and release abcl-1.4.1.  Alternatively you could try
building ABCL from source (there's a [Dockerfile][] which will do it for
ya, but you need to understand Docker Engine a bit to interact with it.

[Dockerfile]: http://abcl.org/trac/browser/trunk/abcl/Dockerfile
