According to /usr/include/liberrno.h on our UNICOS 8 Y-MP, an error code
of 5025 means the following:

    Bad open spec, usually layer

(You should check this with your header files.)  I suspect that this
error message refers to the ffopens() `ControlString' argument, which
has the following value:

    bufa:336:2

I further suspect that the above specification is incompatible, in some
way, with UNICOS 7.  Is there anyone out there who would know?

I suggest you look up the meaning of this argument, find some likely
values, and then try setting the environment variable NETCDF_FFIOSPEC to
them and re-executing the `make test' (the function we've been modifying
first looks at the environment variable).  When you've found a value
that works, you can replace the default value in the function with it.

Please let me know what you find.
