I have been unable to reproduce this behavior on either an SGI under IRIX
4.0.5 or a SPARCstation 10 under SunOS 5.3.  Is the "/../" necessary in both
pathnames to demonstrate the bug?  That is do you not get the error when
running the program from "/somedir" to write data to "/otherdir"?

In trying to reproduce the error, I tried the following on an SGI, for
example, and it worked fine:

    % cd /usr
    % ../upc/new/netcdf/bin/ncgen -o ../home/russ/test.nc -b ../tmp/test.cdl

where on our system each of /usr, /upc, and /home are on different devices,
the latter remotely mounted.
