I don't know anything about netcdf_red.f, so if the error is related
to that code, you'll have to contact the author.

If you're right and the problem is with the type of the PTR variable
in udunits.inc, it should be defined to be a Fortran type that will
hold 64 bits for the Alpha, something like "integer*8":

#ifndef PTR
#   define PTR  integer*8
#endif

I'm also CC:ing Steve Emmerson, the author of udunits.inc, in case he
has additional suggestions.
