Currently, not all MPI-IO packages support complicated MPI derived
datatype used in the implementation of irregular
selection INSIDE HDF5.
DEC 5.x is not supporting complicated derived datatype.

For AIX 5.1 64-bit,
regardless of poe version number, please UNCOMMENT

We suspect there are some problems for MPI-IO implementation
for 64-bit.
3) For Linux cluster,
if mpich version is 1.2.5 or lower, collective irregular selection
IO is not supported, internally independent IO is used.
4) For IRIX 6.5,
if C compiler version is 7.3 or lower, collective irregular selection
IO is not supported, internally independent IO is used.
