Wow, sounds like you've done some interesting things, and it's interesting to see that you got it to work at all with a copying collector.

I do advocate making the
official Emacs compile with G++ with the -fpermissive option, to help
further experiments.

What changes would this entail? If you're already running Emacs through a C-to-C++ converter, why can't the converter arrange for the changes itself?

 - dumping (I'm currently using CANNOT_DUMP=yes. Is that supposed to
work? Because it doesn't without a few changes to the initial Lisp

It is supposed to work. Admittedly it's not tested much. We really need to move away from the current dumping model anyway, so CANNOT_DUMP mode will grow in importance (in some sense).

[1] - there's one place that uses "false" for "NULL"

Please let us know where, and we'll fix it.
