[svn-r1065] Changes since 19990121

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

./configure.in
./acconfig.h
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
./src/H5public.h
./src/H5Omtime.c
	Check for <stddef.h>

	Checks for `__tm_gmtoff' in `struct tm' because old versions
	of GNU libc are different than recent versions. This fixes the
	failing mtime test.

./bin/config.guess
./config/freebsd2.2.7	[REMOVED]
./config/freebsd	[ADDED]
	Changed the name so it works with all versions of FreeBSD.

./src/H5.c
	Moved H5F after H5T and H5G in H5_term_library() to satisfy
	dependencies.

./src/H5G.c
	Fixed a bug that caused H5Gcreate() to fail if the group name
	had trailing slashes.

./src/H5Gpublic.h
	Changed `group_name' to `name' in a prototype.

./src/Makefile.in
	Dynamic library on Linux, but needs for work to be generally
	useful.

./src/H5HG.c
./src/H5HGprivate.h
	Fixed alignment problems when using old GCC compilers (like
	the one shipped with RedHad Linux).

./tools/h5ls.c
	Fixed a bug where the contents of the root group could be
	listed twice if there was a link back to the root
	group. Similarly for groups that are mentioned on the command
	line.

	Fixed a bug where unknown types were printed with a random
	type class number.

./src/H5T.c
./src/H5Tconv.c
./src/H5Tprivate.h
	Fixed O(log N) conversion bugs.
