compile problem

[Артемий]

Description:
-----------

octave-2.9.18 and octave-2.9.19 don't compile with hdf5 compiled with mpi 
support. Last error is:

In file included from /usr/include/mpi.h:1110,
                 from /usr/include/H5public.h:54,
                 from /usr/include/hdf5.h:24,
                 from ov.h:34,
                 from oct-obj.h:33,
                 from Cell.h:32,
                 from Cell.cc:29:
/usr/include/mpicxx.h:26:2: error: #error "SEEK_SET is #defined but must not 
be for the C++ binding of MPI"
/usr/include/mpicxx.h:30:2: error: #error "SEEK_CUR is #defined but must not 
be for the C++ binding of MPI"
/usr/include/mpicxx.h:35:2: error: #error "SEEK_END is #defined but must not 
be for the C++ binding of MPI"

comment from mpicxx.h:

// There is a name conflict between stdio.h and the MPI C++ binding
// with respect to the names SEEK_SET, SEEK_CUR, and SEEK_END.  MPI
// wants these in the MPI namespace, but stdio.h will #define these
// to integer values.  #undef'ing these can cause obscure problems
// with other include files (such as iostream), so we instead use
// #error to indicate a fatal error.  Users can either #undef
// the names before including mpi.h or include mpi.h *before* stdio.h
// or iostream.


This error means, that in Cell.cc (and in all other sources in .../src), 
oct-obj.h (include hdf5) is AFTER idx-vector.h (include iostream) included.

Fix:
---

hdf5.h must be included before iostream.
