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

./src/H5Tbit.c
./MANIFEST
./test/Makefile.in
./test/bittests.c	NEW
	Finished the bit vector operations and added test cases.

./src/H5Tconv.c
./test/dtypes.c
	Finished integer->integer general conversion and added test
	cases. Overflows and underflows are handled by substituting
	the closest possible value.  Examples:

	   (unsigned)0xffff -> (unsigned)  0xff
	   (  signed)0xffff -> (unsigned)0x0000
	   (unsigned)0xffff -> (  signed)0x7fff
	   (  signed)0x7fff -> (  signed)  0x7f
	   (  signed)0xbfff -> (  signed)  0xbf
	   (  signed)0x8000 -> (  signed)  0x80

./src/H5private.h
	Added definitions for MIN and MAX that take 3 or 4 arguments:
	MIN3(), MIN4(), MAX3(), MAX4(). Also added MIN2() and MAX2()
	as aliases for MIN() and MAX().

./test/tattr.c
	Removed some redundant `&' operators.

./configure.in
./src/H5config.h.in	[regenerated]
./src/H5.c
	Fixed warnings on DEC where long double is the same as
	double.
