./configure.in

./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
	Added checks for functions, structs, constants, and header
	files used in h5ls.c to determine the output width with
	various Windows compilers and Unix variants.

	Added check for <sys/stat.h> and defined
	HAVE_SYS_STAT_H. Included <sys/stat.h> in H5private.h outside
	the Posix.1 #include's section.

./src/H5RA.c
	Less aggressive about failing -- rather returns false, which
	allows type detection to continue.

./src/h5ls.c
	Data types are displayed for datasets and named data types when
	`-v' or `--verbose' is specified on the command-line.  The
	algorithm is a little different than the dumper because we're
	trying to be human-friendly, not necessarily machine-friendly.

	   * Any data type which matches a native C type gets printed
	     something like `native double'.

	   * A floating point type that matches one of the IEEE standard
	     types but not one of the native types gets printed like `IEEE
	     64-bit big-endian float'.

	   * Other floating point values have information about sign bit
	     location; exponent size, location, and bias; and significand
	     size, location, and normalization.

	   * Padding and offsets are displayed for types that have
	     padding (precision != size), including internal padding for
	     some floating point data types.

	   * Non-native integer types are displayed like `32-bit
	     little-endian unsigned integer'.

	   * Compound data types have each member displayed including the
	     member name, byte offset within the struct, dimensions, index
	     permutation, and data type.

	   * String types are displayed like `256-byte null-terminated
	     ASCII string'.

	   * References are displayed like `8-byte unknown reference'
	     until the reference interface stabilizes a little.

	   * All other types including types not yet defined will be
	     printed like `4-byte class-9 unknown'.

	The dimensionality of scalar datasets is printed like `{SCALAR}'
	instead of just `{}'.

	If external raw files are used to store a dataset then the offsets,
	sizes, and file names of each are printed if `-v' or `--verbose'
	was given on the command-line.

	If an object is found and h5ls can't determine the object type then
	it still tries to print the number of hard links, the OID, and any
	comment that might be present if `-v' or `--verbose' was specified.

	If the `-d' or `--dump' switch is turned on then ragged arrays will
	report that the data can only be dumped by dumping the component
	datasets explicitly.  I'm not planning to implement this since
	we're going to eventually change the whole way ragged arrays are
	stored.

	Compound data values do not have the component names displayed by
	default when `-v' or `--verbose' is turned on.  Instead, the names
	can be displayed with `-l' or `--label'.

	The output width is determined by the first rule that applies:

	   * If the `-wN', `-w N' or `--width=N' switch appeared on
	     the command line then use N for the output width.

	   * Query the OS for the tty width in a highly unportable way
	     borrowed from GNU `less' depending on what functions and
	     data structures were found during configuration (if any):
	     _getvideoconfig(), gettextinfo(), _srcsize(), ioctl(),
	     GetConsoleScreenBufferInfo(), struct videoconfig, struct
	     text_info, the TIOCGWINSZ ioctl, the TIOCGETD ioctl.

	   * If the `COLUMNS' environment variable is set then use
	     its value.

	   * Use the value 80.

	Just for kicks, run Mark and Jim's test_vbt and then say `h5ls -dlsv
	test.vbt'.  You can also try it on the various *.h5 files in the
	test/example directories.

./config/linux
	Removed turning on parallel by default on Robb's macine.
