Yes that's very strange!

Yes that could be added to a makefile somewhere easily enough

Yes certainly wouldn't be much more work at all.

It was really just that I felt that was the way Glynn had designed it and
there would be fewer complications and things likely to go wrong if it is
done that way. I just wanted to minimise the amount of work I had to do to
get it working. But it looks now like it mightn't require many if any
(now) changes to run it from the normal place.

To do:
provide some way of deleting the *.o files.
Move the checks in POST_INSTALL.sh somewhere else (probably into
mk/Makefile?)
Add srcdist and bindist to mk/Makefile
