Even then, I doubt your suggestion will work as autotools and m4 etc are
lacking. AFAIU the bash shell is merely meant to be able to run Octave in
gdb on the Windows side.
It could be that it is fairly easy to augment the bash shell with the
required development tools; on the mingw site compiled build tools are

I was able to compile ffmpeg with the installed tools. make and gcc
are present and the video package had configure script.

Yes I ignored that Octave should be able to install packages and needs some basic tools for that. Nice to know that some dependencies (that are usually built outside Octave) can be built as well.

Although libavformat.dll, libavcodec.dd, etc aren't present in my
