I think you should use -1 in the parameter statements for
nf90_fill_ubyte, nf90_fill_ushort, and nf90_fill_uint. That's the
same value that actually gets assigned using the typeless hexadecimal
constants Z'FF', Z'FFFF', and Z'FFFFFFFF', which are technically
outside the range of signed ints (hence the error message). So -1
gives you the same value without the errors and it's portable.
