Changes since 19990611
----------------------

./doc/html/H5.format.html
	Added documentation for opaque data types (bitfield types were
	already documented but they were out of order).

./src/H5E.c
	Fixed a bug with glibc2 on linux systems where `stdout' is an
	extern and can't be used to initialize static data.

./src/H5T.c
./src/H5Tpkg.h
./src/H5Tpublic.h
./src/H5detect.c
	Removed the `_T' from the new C9x types I just added so the
	names are consistent with existing types. Besides, the fact
	that something is a datatype is obvious because it starts with
	H5T_NATIVE_.

./tools/h5ls.c
	Added the new C9x data types. H5ls prints one of these types
	only if it doesn't match one of the builtin C types.

	Prints the OID for shared data types.

	Fixed a formatting bug with symbolic links which was
	introduced a few changes ago.

	The commandline has been changed so that objects from multiple
	files can be listed with a single command. Instead of
	specifying a file name and an optional list of objects, each
	thing to print is a file name and object concatenated. H5ls
	figures out how to devide the name into a file name and object
	name even when the file name part doesn't correspond to an
	actual Unix file.

	   Old syntax: h5ls [OPTIONS] FILE [OBJECTS]
	   New syntax: h5ls [OPTIONS] FILE[/OBJECT] [FILE[/OBJECT]]...

	   Example ({X,Y} is expanded by the shell)

	   Old command: h5ls -d ../test/x.data dir1 dir2
	   New command: h5ls -d ../test/x.data/{dir1,dir2}

	The filename is printed as part of the object name when full
	names are requested (--full or --recursive). If people really
	don't like this they can undefine a constant at the top of
	h5ls.

	Errors from the hdf5 library are turned off.

	Commandline switches of the form `--width 80' are accepted in
	addition to `--width=80'. This is more symmetric with
	single-letter switches that take two forms: `-w 80' and
	`-w80'.

./src/H5D.c
	Added tracing instrumentation for H5Dvlen_reclaim().

./src/H5private.h
	Added casts to int for the isalpha() et al macros to shut up
	solaris warnings about char subscripts.
