bug fix
Description:
the fletcher filter used a temporary 2 byte word buffer to compute the checksum.
this is non portable between big-endian/little endian.
Solution:
replaced with a buffer of 1 byte type
Platforms tested:
linux
solaris
solaris 64 bit
AIX
windows

Incremented the release number. The previous one is used
by the fphdf5 alpha0 release.
Platforms tested:

Code cleanup/bug fix
Description:
Fix configuration files to allow 64-bit compilation of the library with
a 64-bit version of zlib.
Solution:
Moved important compiler flags settings from CC macro to CFLAGS macro.
Instead of setting CC (F9X, CXX) environment variable for compiling for 64-bit
code, users should just set the CFLAGS (FFLAGS, CXXFLAGS) to -q64.
Updated INSTALL file to reflect this change.
Platforms tested:
IBM p690 (copper) w/parallel, FORTRAN, C++, srcdir.
Platforms specific - h5committest does not apply.

Bug fix/optimization
Description:
Address slowdown in MPI-I/O file metadata operations that was introduced
mid-stream. We now _require_ a POSIX compliant parallel file system for the
MPI-I/O file driver (as well as for the MPI-POSIX file driver).
Also optimized file open operation when the file is being created by
reducing the number of collective & syncronizing calls.
Additionally, refactor the MPI routines into a common place, eliminating
duplicated code.

Bug fix
Description:
Correct two problems with variable-length datatypes in datasets:
- When overwriting an entire dataset, writing the fill value to the
file would be skipped, causing problems for VL datatypes when
objects in the file had been unlinked (and thus the space in the
file was not all zeros)
- When an application has set a fill-value for a dataset and the
dataset's datatype contained a VL datatype, the library was filling
space on disk with the memory form of the VL information, instead
of the disk form.

Bug fix
Description:
When two property lists are compared, the H5Pequal routine was just
comparing the raw information for the property values. This causes problems
when the raw information contains pointers to other information.
Solution:
Allow a 'compare' callback to be registered for properties, so that a user
application get perform the comparison itself, allowing for "deep" compares of
the property value.
This was exported to the H5Pregister & H5Pinsert routines in the development
branch, but not the release branch.

Bug fix
Description:
Variable length strings and sequences with NULL pointers were not handled
by library, causing problems access the data. This also affected fill values
for variable-length datatypes.
Solution:
Address the issues in the library by detecting NULL sequences/strings
and avoid trying to convert them.
Patched up dumper to display NULL sequences/strings.

Code optimization
Description:
Improved integer & floating-point datatype conversions by removing some

convert backwards, switching to algorithm which computes the non-overlapping
space in the buffer and repeatedly converts it in the forward direction.

Improvement
Description:
If the library is built in parallel mode, then name the "h5cc" and
"h5fc" programs "h5pcc" and "h5pfc" resp. This saves the user from
worrying about mixing serial and parallel builds of the library and
having to specify the pathnames and so-forth.

Bug fix & code cleanups

Bug fix
Description:
Single hyperslab selections (which were set with only one call to
H5Sselect_hyperslab) that had dimensions that could be "flattened" but were
interspersed with dimensions that could not be flattened were not correctly
handled, causing core dumps.
Solution:
Re-work "flattening" code to handle this case properly.
