We surely want them distributed. We also want to distribute the generated
wrapper (for those not having unstable swig installed).
Would be nice if make maintainer-clean would get rid of the latter
and next make would recreate it.

A rule of thumb for the C API is:
Every Geometry caller should take care of is returned
as a non-const object.
For these specific case the caller must delete them.
