Sounds dangerous (void **) but before thinking about external
extensions, we might benefit from this to have postgis_raster and
postgis_topology share liblwgeom, if you want to experiment with that.

I'm still not sure why we didn't want liblwgeom to live on the system
and be dynamically linked by all those extensions of ours at least,
which would solve the same problem in a more standard and simple way.
