Here's what Steve Emmerson suggests:

  The solution is to configure the file "f90/netcdf_overloads.f90" so
  that: 1) it doesn't use any primitive types that aren't supported; and
  2) the signatures of all the routines that the file defines are unique.

  The problem is that there's no standard macro capability in Fortran-90.
  This means that the appropriate configuration of the file must be
  determined by the configure script and the configuring process must be
  implemented using UNIX utilities (e.g. cpp, sed). I haven't had time to
  do either.

  He should have been able to manually modify the file in order to
  successfully compile it.

So, sorry, we haven't gotten to this yet.  (We currently have only 1/4
person available for netCDF support and none for netCDF development,
but we're hoping for more resources soon ...)
