Description: Mac OS 10.4 on PowerPC chip has some errors to convert (unsigned)
long long to long double. When the bit sequences are 0x003ff..., 0x007fff...,
0x00ffff..., 0x01ffff..., 0x7fffff..., the converted values are twice as big
as they should be.
Solution: Detect the error in configure and disable the compiler conversion
and test case.
Platforms tested: h5committest, Mac OS 10.4, and fuss.

Configuration feature
Description:

Solution:
Previously, shared libraries were only tested when static libraries were not installed.
Also cleaned up line in commence.am that was including HL library in all Makefiles.

Description: Data conversion from long double to (unsigned) long long
returns some incorrect values on Mac OS 10.4 and SGI IRIX64 6.5. The
conversions start to go wrong when the long double is
20041683600089727.779961 (0x4351ccf385ebc8a0bfcc2a...). If adjusting
the values higher by assigning 0x...c8a0cf... or 0x...c8a0df..., the
converted values go wild.
Solution: Detect this error in configure.in and disable compiler
conversions from long double to (unsigned) long long for Mac OS 10.4
and IRIX64 6.5.
Platforms tested: h5committest, Mac OS 10.4, and IRIX64 6.5.

Code checkpoint
Description:
Add in more new features for the fractal heap code, mostly bringing in

features)

Some collective chunk IO macro names are confusing, change them to more meaningful
names.
Description:
H5Pset_dxpl_mpio_chunk_opt will set a flag so that the library can do one linked IO or multi-chunk IO with collective in chunking storage directly. That is, the library won't do analyses to determine this.
The flags for the enum type we used before are:
H5FD_MPIO_OPT_ONE_IO
H5FD_MPIO_OPT_MULTI_IO
They are not good names because of the following two reasons:
1. It doesn't reflect chunking storage
2. OPT is kind of redundant and misleading,
Solution:
We change the names to
H5FD_MPIO_CHUNK_ONE_IO
H5FD_MPIO_CHUNK_MULTI_IO
Platforms tested:
Since only macro names are changed, no need to test with h5committest.

1) Check in potential fix to unreproduceable bug in t_cache observed on
Cobalt
2) Check in code supporting added pinned entry features in the metadata
cache.
Description:
1) Elena encountered a bug in t_cache when running on Cobalt. On
investigation I found a potential race condition in t_cache that
could explain her observation.
2) Quincey requested additions to the metadata cache allowing renaming
of pinned entryies, and marking of pinned or protected entries as
dirty.
Solution:
1) Modified t_cache.c to prevent the potential race condition. Elena
was unable to reproduce the bug on Cobalt, so we don't know if my
fix actually addressed the problem.
2) Added code supporting the requested functions. The changes were
relatively trivial, but required substantial new test code.
Platforms tested:
h5committest, serial test on heping, parallel test on phoenix.

Bug fix.
Description:
The ${TR}, though avoid the error, is inconvenient. It is needed
because configure.in use the char range in the style of 'a-z'.
The other style of '[a-z]' is more commonly accepted by all tr
but autoconf tends to strip away [], making the syntax rather
clumsy.
Solution:
Learned from autoconf that it avoids the use of character range
by just spell all the letters out. Changed our tr commands to
use those variables defined by autoconf. Also removed the
definition of ${TR} since it will cause inconsistancy when
autoconf also use plain 'tr' in its generated code.
The Makefile.in are changed because the elimination of ${TR} from
configure triggered its removal from all Makefil.in. That is okay
because ${TR} is not used at all in Makefile.
Platforms tested:
h5committested. (sol failed to connected). also tested in shanti
using both /usr/ucb/tr and /bin/tr (the bad one before.)
Misc. update:

Bug fix.
Description:
Some machines (e.g., HPUX) will have off64_t defined but no support
for stat64 unless certain LargeFile macro is turned on. This caused
the last fix on H5private not quite right which caused compiling failures.
Solution:
Added stat64 and fstat64 tests and then will use them only if they
are supported.
Platforms tested:
Tested on kelgia, copper and heping (pll).
(Compiling alright but tests for kelgia and heping are not done.

Bug fix for collective chunk IO
Description:
Several options have been provided inside HDF5 library for
obtaining chunk addresses when doing collective chunk IO.
One option is to obtain chunk addresses for one process and broadcast
to other processes. This option needs all processes to participate.
If using link-chunked IO without any optimizations,
sometimes this is not true due to the random initialization for one variable at mpich 1.2.7.
This is a bug inside the collective chunk IO code.
Solution:
1.Initalize all the variables to some safe numbers,
2. Avoid using MPI broadcast to obtain the chunk address if possible
until more performance studies have been done.
3. Seems okay to obtain chunk addresses individually for each processor.
This option may cover most cases.

bug fix.
Description:
Previous H5private.h would attempt to use the off64_t/stat64/etc
by checking just sizeof __INT64 being 8. This caused errors in
some machines like alpha cluster which is a 64bit machine. Its
compiler supports the type __int64 but it does not support
off64_t since its off_t is already 64bits big. The above code
casued the compiler to complain about the unknown off64_t and
such.
Solution:
H5private.h:
Changed the code to use the pseudo standard of off64_t/stat64/etc
only if sizeof(off_t) is not 64 bits AND sizeof(off64_t) exists
and is 64 bits. This assumes if off64_t is defined, all those
stat64, fstat64, etc are supported too.
configure.in:
configure:
Added the testing of sizeof(off64_t) to support the above solution.
Platforms tested:
h5committested. Also tested at LANL QSC.
