ODR violation: dropped a const?

[havogt]

I got the following warning with gcc 9, didn't look into the problem, but could be a problem in cpp_bindgen:

cosmo/dycore/src/dycore/Bindings/dycore_base_bindings_float.h:125:6: warning: ‘gt_tracer_add_metainfo0’ violates the C++ One Definition Rule [-Wodr]
