[svn-r337] Changes since 19980403

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

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

./config/linux
	Prints a warning if the gcc version is less than 2.8.1 since
	that version has problems with register allocation for `long
	long'.

./html/Datatypes.html
	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.
