[vtk-developers] Mpi compile broken when using mpich2

[Wylie, Brian]

All,

The following error occurs in 5 different places when trying to compile
VTK with mpich2...

// 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.  

#ifndef MPICH_IGNORE_CXX_SEEK
#ifdef SEEK_SET
#error "SEEK_SET is #defined but must not be for the C++ binding of MPI"

The patch file is attached...

I'll check in the changes momentarily...
