Ok, I see the problems. I looked hoping to find a Makefile fragment I can
include but it seems I need to modify the sane Makefile.in and run configure
again. Not quite as stright forward as I hoped. Is there a better way?

Oddly enough it's sane-debug.h that renaming all my functions in the
library. Very odd.

Same in my Makefile except I obviously picked the wrong values. Looks like I
need to learn how to use those test tools.
