Yup, I figured that out! I'm still not a C programmer but my hacker
skills are improving. I ended up grep'ing through /usr/include for
Z_BEST_COMPRESSION and found that zlib.h had what I needed. I checked
upstream and the master branch already has the fix but the (updated)
0.10.3 still does not. I'm doing a local mock build to make sure my
patch works.

Thanks,
