[svn-r1010] Changes since 19981217
----------------------

./src/H5.c
./src/H5private.h
        Renamed `library_initialize_g' to `H5_libinit_g' to make it
        conform to our naming scheme.

./src/H5I.c
        Fixed a bug in H5I_dec_ref() that caused the return value to
        always be zero instead of the new reference count.

./src/H5.c
./src/H5Odtype.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
        Added support for enumeration data types.

./src/H5RA.c
        Renamed H5T_insert() to H5T_struct_insert() and added
        H5T_enum_insert().

./src/H5RA.c
./src/H5Shyper.c
        Added casts to size_t for the third argument of memcpy() to
        shut up a warning message from insure++.

./src/H5T.c
        Changed "can't" to "unable to" in some error messages to be
        more consistent.

./src/H5detect.c
        If fork() or waitpid() are unavailable then we assume no
        alignment constraints. Hopefully this is the case only on NT
        and Intel CPU's don't have alignment constraints.

./src/H5public.h
        Include <limits.h> because the H5T_NATIVE_CHAR macro needs the
        definition for CHAR_MIN.
