unfortunatly, the original objc-lang.c botched its portability(1),
sigh! The file is currently native only so infrun.c can't directly
refer to objc-lang.c, and hence, will need to go via a dispatch table.
Going via a dispatch table wouldn't hurt anyway.
(1) I noticed that the parameter extract methods assume host=target.
I'm wondering what's not portable with objc-lang.c? With the remaining
patches I have that require this, I was thinking it might be easier to
just fix it now. The alternative appears to be adding a whole bunch of
things to the language_defn structure. I admit I don't really
understand the problem though.
