It should be possible to build the netCDF package using the the IRIX
Fortran compile with the "-r8" option (I just did this).  After that, it
should be possible to use the ...VAR_REAL routines to access NF_FLOAT
data.

Note that the Fortran-90 interface of the the netCDF library cannot be
built if the "-r8" option is used.

Please keep me apprised.
