Comment (by Roland Haas):

This pull request contains a workaround for master:

https://bitbucket.org/cactuscode/cactus/pull-requests/109/cactus-test-full-cctk_pointerto-function

it ends up testing the full code for CCTK_PointerTo in configure and only enables it if it compiles. Compilers that do not support it are assumed old enough to not enforce consistent arguments to Fortran subroutines and the flesh falls back to the pre-gfortran-10 code for CCTK_PointerTo in the same way it does if a compiler does not support type(*) or dimension(..).
