[svn-r323] Changes since 19980316
----------------------
./src/H5D.c
./src/H5T.c
./src/H5Tprivate.h
Fixed a bug found by Kevin Powell regarding preservation of
existing data during a read or write when the source and
destination data types are the same. Thanks Kevin!
Fixed a couple warnings on Irix64.
./src/H5D.c
./src/H5Dprivate.h
./src/H5P.c
./src/H5Ppublic.c
./src/H5Tconv.c
./src/H5Tpublic.h
./test/cmpd_dset.c
The application can now turn on/off the part of the I/O
pipeline that deals with preservation of initialized data.
The default is off since this will be the usual case and
turning it on slows down the pipe. Use H5Pset_preserve() and
H5Pget_preserve().
./src/H5Fistore.c
Added an optimization for reading/writing a single chunk of
chunked storage.
./src/H5Odtype.c
./src/H5Oefl.c
./src/H5Olayout.c
./src/H5Oname.c
./src/H5Osdspace.c
./src/H5Ostab.c
Fixed warnings reported by marek@iiasa.ac.at. Thanks Marek.
./src/H5Odtype.c
Fixed a failing assert() wrt reading compound types (not
present in hdf5-1.0.0a).
