Dag, I still have problems with this (the 'sizeof(int[3])' part):
cdef inline object newarray_int3(int n, int (**p)[3]):
if n < 0: n = 0
cdef int (*array)[3] # = NULL ## XXX
cdef object ob = allocate(n*sizeof(int[3]), <void**>&array)
^

/u/dalcinl/Devel/Cython/mpi4py-dev/src/MPI/asarray.pxi:13:44: Expected: type
Please, do not blame me for being too pedantic. I have to deal with
this because I need to wrap some MPI calls like the following:
int MPI_Group_range_incl(MPI_Group group, int n, int ranges[][3],
MPI_Group *newgroup)
It has been really hard for me to find an alternative way do build the
'ranges' arguments avoiding Cython or C compiler errors/warnings.
However, perhaps I could change sizeof(int[3]) to 3*sizeof(int). It
seems it should be equivalent, but I'm not completelly sure? Can
someone comment on this?
