animated-paintable and peg-solitaire I had not tried last time and
they are the ones that crash.

Yes, they had not worked previously, and now with your long-name fix,
they work.

Yes, after 5 minutes animated-paintable.scm crashes.  Hmm.

Yes, but still it is much better that I can now soon rewrite my
trivial Kodi launcher to use g-golf instead of C.  Having to
use a virtual machine meant I could not reasonably put g-golf to use
