That was nearly right but not quite.
Because I know so little about such things it took me quite a long time (with
various not quite helpful leads from google). Eventually I discovered the fix.
It should have been

With that change it compiles on my F22 desktop machine.
./ctwm -version
prints out "3.8.2-post"
I assume you'll install that, though I don't know how it will affect
other versions of linux.
I wonder whether I can switch from the old running version to this newly built
one to test it without having to log out and log in (which would be very
disruptive) if I replace the old ctwm binary with the new one and then invoke
the f.restart function via the menu option I had set up to invoke it?
Anyhow, I'll try to test it soon.
A remaining mystery is why I can't build the new version on my laptop also
running fedora 22. I may have some paths set up incorrectly or some missing
libraries, which I'll check out more carefully when I have more time.
