The above message contained the following:

The include-file "/home/sapir/udunits-1.12.1/include/udunits.inc"
defines the types of UTMAKE, UTDEC, and UTTIME -- so it's not necessary
(and apparently an error) to define them within the "gridread"
subroutine.  If you remove the following lines

>      integer UTMAKE !!!!this is line 271
>      integer UTDEC,uttime

from the "gridread" subroutine, then the file should compile without the
following errors:

Apparently, the Portland Group Fortran compiler doesn't care how many
times a symbol is declared as long as the declarations are the same.
