This is a problem with the UDUNITS package rather than the netCDF

What is the size of a C pointer on the SUN UltraSparc Enterprise 10000?

What is the Fortran integer that is the same size?

You should declare the return type of the Fortran function "utmake"
to be this type in the file "udunits.inc". You must also declare all
variables in your Fortran programs that hold a return value from
"utmake" to be this type.
