Thank you very much for handling these breakages.

I much prefer this version over the other.  It's incremental, and
doesn't add any hack or reference to the current_target global.

Mostly, because it's a bunch of work that affects most native
targets.  I tried hard to avoid missing any conversion in
the last set of changes, but, it ended up I broke a lot
of stuff...  But, yeah, there's a lot of inconsistency
here.
