----------------------

THIS CHECKIN IS FOR QUINCEY -- NOT EVERYTHING WORKS (but it compiles)
MOST OF THE CHANGES ARE FOR BETTER TYPE CONVERSION IN THE NEXT ALPHA

./MANIFEST
./src/H5Tbit.c		NEW
./src/Makefile.in
	Bit vector operations (not done yet)

./configure.in
	Added -lm to the library list, needed by bit-vector operations
	and conversion functions.

	Removed vestiges of PARALLEL_SRC no longer used by the
	makefiles. Albert came up with a better way (that actually
	works :-)

./src/H5D.c
	No code changes.  Split a couple of long lines, refilled a
	couple multi-line comments.

./src/H5T.c
./src/H5Tpublic.h
	Fixed a bug reported by Jim Reus regarding conversion of
	compound data types whose members require conversions which
	are satisfied by as-yet unregistered soft conversion
	functions.

	Added H5T_IEEE architecture, but the funny-looking integer
	types will be changed to H5T_BE_ and H5T_LE_ architectures
	with the type names changed to match the H5T_NATIVE_ integers.

	Added an H5Tconvert() but it hasn't been documented or tested
	yet.

./src/H5Tconv.c
./src/H5Tpkg.h
	Registered conversion functions integer->integer (a general
	case) and integer->float (for a specific case).  The
	integer->integer conversion depends on the bitvector
	operations which aren't finished yet and the int->float
	conversion hasn't been retested since it was borrowed from
	AIO. Don't look at them yet, they're ugly :-)

./src/H5detect.c
	Fixed a typo which caused the msb_pad field of an atomic type
	to not be initialized.

./test/dtypes.c
	Added a test for number conversions but it's commented out
	until the conversion stuff is truly working.
