Log Message:
Update to version 1.4.5.

Changes:

* Allow scalar dataspaces to be used for parallel I/O.  QAK - 2002/11/05
* Added environment variable "HDF5_DISABLE_VERSION_CHECK", which disables
  the version checking between the header files and the library linked
  into an application if set to '1'.  This should be used with caution,
  mis-matched headers and library binaries can cause _serious_ problems.
  QAK - 2002/10/15
* Partially fixed space allocation inefficiencies in the file by
  improving our algorithms for re-using freed space.  QAK - 2002/08/27
* API tracing has been improved. Nested API calls don't screw up the
  output format; function call and return event times can be logged;
  total time spent in each function can be logged.  The following
  HDF5_DEBUG environment variable words affect tracing:
	trace   -- turn on/off basic tracing
	ttimes  -- turn on tracing and report event times and
                       time spent in each API function.
        ttop    -- turn on tracing but display only top-level
                       API calls.
* Several missing fortran APIs have been added to the library:

   h5get_libversion_f        h5tget_member_index_f  h5dget_storage_size_f
   h5check_version_f         h5tvlen_create_f       h5dvlen_get_max_len_f
   h5garbage_collect_f                              h5dwrite_vl_f
   h5dont_atexit_f                                  h5dread_vl_f

Functions h5dvlen_get_max_len_f, h5dwrite_vl_f, and h5dread_vl_f support
VL Length C APIs functionality for integer, real and string datatypes.
See HDF5 Reference Manual and HDF5 FORTRAN90 User's Notes for more
information and for the functions description.

* H5Fopen without the H5F_ACC_CREAT flag should not succeed in creating
  a new file with the 'core' VFL driver.  QAK - 2003/01/24
* Corrected metadata caching bug in parallel I/O which could cause hangs
  when chunked datasets were accessed with independent transfer mode.
  QAK - 2003/01/23
* Allow opening objects with unknown object header messages.
  QAK - 2003/01/21
* Added improved error assertion for nil VL strings.  It return error
  stack instead of a simple assertion.  SLU - 2002/12/16
* Fixed h5dump bug(cannot dump data and datatype) for VL string.
  SLU - 2002/11/18
* Fixed error condition where "none" selections were not being handled
  correctly in serial & parallel.  QAK - 2002/10/29
* Fixed problem where optimized hyperslab routines were incorrectly
  invoked for parallel I/O operations in collective mode.  QAK - 2002/07/22
* Fixed metadata corruption problem which could occur when many objects
  are created in a file during parallel I/O.  QAK - 2002/07/19
* Fixed minor problem with configuration when users specified /usr/include
  and /usr/lib for the --with-* options that some compilers can't
  handle. BW - 2003/01/23
