[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.
