Hey!... Isn't that the model of DA's in petsc-dev? My current issues
in petsc4py are more realted to backward compatibility than anything.
But even if I manage to remove the #define DA DM, petsc4py will still
use DA for the class name (unless there is some strong arguments from
any of you).

I you use the new DMDAxxx API' from petsc-dev, you should not need
petsc4py/src/include/custom.h at all... It is just the #define DA DM,
and that is required only for the case of using "cimport" in Cython
code (I mean, SWIG wrappers or hand-written C should not suffer from
this issue).
