[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. ./src/H5AC.c ./src/H5ACprivate.h ./src/H5D.c ./src/H5E.c ./src/H5Eprivate.h ./src/H5F.c ./src/H5Farray.c ./src/H5Fcore.c ./src/H5Ffamily.c ./src/H5Fistore.c ./src/H5Flow.c ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5Fsec2.c ./src/H5Fstdio.c ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5HG.c ./src/H5HL.c ./src/H5HLprivate.h ./src/H5I.c ./src/H5Iprivate.h ./src/H5MM.c ./src/H5MMprivate.h ./src/H5O.c ./src/H5Oefl.c ./src/H5Oprivate.h ./src/H5Osdspace.c ./src/H5Oshared.c ./src/H5Ostab.c ./src/H5P.c ./src/H5S.c ./src/H5Ssimp.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tprivate.h ./src/H5Tpublic.h ./src/H5V.c ./src/H5Vprivate.h ./src/H5detect.c ./src/h5ls.c ./test/cmpd_dset.c ./test/dsets.c ./test/external.c ./test/hyperslab.c ./test/iopipe.c ./test/istore.c ./test/shtype.c ./test/tstab.c Fixed comparisons between signed and unsigned values. Fixed warnings about unused function arguments.
