Some OS's have problems with large arrays created on the stack and I
had forgotten about that when I wrote this test.

When configure with enable-paralle, H5detect and debug were not
compiled with $(LIBS) but were executed via RUNTEST (mpirun ...).
The O2K mpirun can't handle such an object code.
Solutions:
Compile them also with $(LIBS) which contains the mpi library names.
Could have just removed $(RUNTEST) but in some parallel system, all
object file may have to be launched by some mpirun-equivalent command
anyway.
Platforms tested: O2K

Added modification entry to H5F_open header. Should have been done
when i added the access template argument.
H5Fprivate.h:
The hardcode setting to "define MPIO as the default IO
when HAVE_PARALLEL is set" cause all test programs to fail since
none of them is coded with the needed MPI_Initialize. Change it
back to the previous setting of using sequential I/O allows user
to use sequential I/O by default and use MPIO only if he/she explicitely
asks for it via access template setting.

No harm, just looked strange. Removed 'all' from the second
appearance. Tested in a O2K.

Changed default RUNTEST to 'mpi -np 1'.

Use $(RUNTEST) to run programs if enable-parallel is on.

file does not exist, the code tried to open the file with EXCL CREATE.
ROMIO cannot handle file-open with EXCL Create due to racing problem.
The first process creates the file which then fails all
other processes.
Solution: In the parallel code, turn on TRUNC mode to allow "late" open
calls to succeed too. It is safe to force TRUNC mode since the file is
known non-existing at that point. The MPIO implementation has to
provide the real solution.
Platform tested: O2K with ROMIO.

Problem: Data type handle was not released.

offset and length to 4. Will fix the problem later.

h5_write.c - stores INT array as INT32 little endian dataset in the HDF5 file.
h5_read.c - gets info about the dataset;
reads hyperslab from the dataset in the file into
2-dim slice of the 3 dimensional array.
h5_compund.c - creates compound dataset and writes it to the file;
reads subsets of the dataset.
h5_extend_write.c - writes extendable dataset.
h5_extend_read.c - gets info about the dataset;
reads dataset and one of the chunks.
