PS1, Line 132:

Yeah. I'm not too familiar with this code, but it seems a bit messy.

I think this is an artifact of old changes. The comment makes it sound
like we may not include maverick, but Makefile.in includes it
unconditionally.

In this case, i think having the definition in maverick.c and having
it external in wrapper.c makes more sense.
