I don't claim it's a better solution, really.  I just don't see anny
movement towards providing libffi support (other than people saying we
should do it).

I think the reason is that I don't know anyone who's willing/able to add
libffi support to Emacs and write the corresponding code to link to
(say) libgnutls.

Whereas the path I suggest only involves steps which I'm pretty sure
many people here can do without much trouble.

See, "you should find lots of help for that here".
