Changes since 19990430
----------------------

Remove changes from CVS

./bin/release
	Added a `--nocheck' switch which causes the script to not
	check the contents of the MANIFEST file against CVS. This is
	sometimes useful when you need to make a quick snapshot but
	the MANIFEST file is not quite up to date.

./src/H5D.c
	Removed warnings for unused variables

./src/H5Fprivate.h
	Removed the WIN32 definition for `uint' and changed the data
	type for `eof_written' from `uint' to `uintn'. Shouldn't this
	really be `hbool_t'?

./src/H5Odtype.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tpublic.h
./test/dtypes.c
./doc/html/H5.format.html
	Added support for bitfields and opaque data types.
