./configure.in
	Moved setting of compiler warning switches earlier in the file.
	Turned on more warning switches to gcc.

	Documented sharing of data types between datasets.

./src/H5G.c
./src/H5Gpublic.h
	Implemented H5Gmove(), H5Glink() and H5Gunlink() for hard
	links.  Still have soft links to do.
