Comment (by Roland Haas):

Pull request is here: https://bitbucket.org/eschnett/carpet/pull-requests/48/carpet-prefix-public-functions-with-carpet

For C code this should be source code compatible since it uses a couple of #define to map CallScheduleGroup to CarpetCallScheduleGroup but the Fortran interface defined using CCTK_FNAME(CallScheduleGroup) cannot be fixed that way since Fortran code does not (tend to) include any header file.
