Changes since 19990618
----------------------

./configure.in
./configure		[REGENERATED]
	Now that compound struct conversions don't make so many calls
	to convert their members I turned the H5T debugging back on by
	default (it will still be disabled in a production version).

./src/H5AC.c
./src/H5B.c
	Made it possible to turn off messages about debugging these
	two packages using the same method as for all other
	packages. Just supply an invalid file descriptor number or use
	the shell to redirect said descriptor to /dev/null like this:

	    $ HDF5_DEBUG=99,ac,b 99>/dev/null a.out

./src/H5T.c
	Changed the name of the old compound conversion function from
	`struct' to `struct(no-opt)' to be more consistent with the
	new version named `struct(opt)'.

	Fixed a bug in H5T_cmp() that caused any two VL types to
	compare as being equal.

	Removed duplicate code for bitfield comparisons in H5T_cmp().

./src/H5Tconv.c
	Relaxed some constraints in the new compound conversion
	function so it applies to more cases.  Also eliminated a
	memcpy in a tight loop.

./test/cmpd_dset.c
	Added a `--noopt' command line switch which unregisters the
	optimized compound conversion so we can test the non-optimized
	version.
