Bug fix
Description:
The symbol "RAW" is already defined in some ioctl.h files.
Changed it to RAWIO.
Platforms tested:
Tflops.
(I am commiting this from TFLOPS. Will check it out immediate
to test on local machines.)

Bug fix.
Description:
Put in the Bug fix Kent applied to v1.5 (use HDfstat instead of just
fstat.)

Code cleanup
Description:
Platform dependent code related to the struct stat and fstat
calls polluted source codes. Hard to maintain.
Solution:
Platform dependent code are moved to H5private.h and then internal
code can #include H5private.h. Repeat those macro definition for
the stdio and multi drivers since they area examples for writing
a virtual file driver. They must not use any internal code.
Platforms tested:
eirene (parallel), modi4 (serial including gass driver.)

Bug Fix
Description:
So, for Raw I/O in parallel, if you open a file with truncation by
multiple processes, it looks as if one process could open the file
and start writing to it while another process also opens the file
with truncation, thus wiping out all of the stuff the first process
wrote to the file.
This is bad.
Also added some garbage collection to the pio_perf routine to reclaim
the space taken by some of the tables.
Solution:
Placed an MPI_Barrier() statement after the Raw open()/create() call
so that all processes are synced up before they start writing to the
file.
Added free() calls to the tables which weren't being free'd.
Platforms tested:
Linux-pp (eirene)

Bone-headed Bug Fix
Description:
There were blanks being put into the output. The cause: the
"print_indent()" routine was printing indents for all of the
processes, but only process 0 should have been printing them out at
all (since process 0 is the one which prints out the reports).
Solution:
Check to make sure that we're process 0 before printing the indents.

updated the Dependencies files via "gmake depend".
Some how this must be done with --srcdir configure option. That is odd.
Platforms tested:
visual inspected "cvs diff" output.

Change default actions.
Description:
Change the default maximum number of processes (-P) to use all processes
instead of just 1 (old default). Someone most likely wants to test
the I/O performance with all processes involved.
Also starts performance measurement with maximum number of processes
and decrement it with each loop. If the performance measurement
needs to restart, it can run with fewer processes if those loops
have completed.
Platforms tested:
modi4 and eirene.

Remove perf and mpi-perf from the parallel test targets since their
functions are replaced by pio_perf.
Platforms tested:
modi4 and eirene, both parallel modes.

Extension
Description:
int64_t type is not available everywhere.
#include H5private.h which has platform dependent hooks
to define int64_t to something available.
Platforms tested:
Tflops, modi4 (parallel), eirene(PP)

Purpose:
Bug Fix
Description:
int64_t was being used as a type for some of these. However, some
platforms don't have int64_t defined.
Solution:
changed them to "long" instead.

Removing the DPSS (gridstorage) driver source code.
(same as the v1.5)
Description:
The DPSS (using Grid-Storage) driver is retired.
Removed the configure option with-gridstorage from configure.in.
Cvs remove the following files
./src/H5FDdpss.c
./src/H5FDdpss.h
./test/dpss_read.c
./test/dpss_write.c
Regenerated Dependencies files (some had to be hand-edited since
'make depend' did not cover them.)
Removed reference to DPSS Virtual file driver from H5F.c.
Platforms tested:
modi4 (Parallel; -with-gass=...)
eirene (pthread safe)
arabica (fortran, cxx).

New feature.
Description:
Test programs were assumed to be serial programs only.
There was no provision to test parallel programs automatically.
Solution:
Added $(TEST_PARA_PROGS) to hold parallel test programs and
added appropriate action entry to test them if defined.
Platforms tested:
Eirene (parallel, serial).
