Recent check-ins have changed some things.  The compile side was working for a
while, but not the compilation side (using it).

I've been working with RP on IRC, and he's come up with some additional patches.
 (including this set of 4..)

So I think the set is fine, it's up to the other pieces that need to mesh with
this to produce the working SDK.
