They're as portable as they need to be.  There's nothing at all to
prevent one from being written in standard Forth.  It's just
generating a bunch of bytes, after all.  Most people don't bother
because they're targeting Forth X from Forth X.

It's only portable in the sense that it'll port to the exact same
assembly language on the same processor.  That's a hell of a
definition of "portable".

In which case I'd like to see someone defend it.  For bootstrapping
it's perefectly reasonable, but after that, no.
