That's very true. Unfortunately, AFAIK there is no Free high quality
cross platform GUI for Lisp :-)

Only the Emacs header files that the display engine needs must be
acceptable by g++. The .c files would be compiled by gcc as usual.

I see. That's probably one instance of the "tight coupling" I was
talking about before.
Apart from reading all the source code, I hope that it is possible to
look into just a few header files for learning the interface of the
display engine.
