    I suggest trying to use the system-supplied XDR stuff rather than
ours.  The problems with XDR on VAXen that prompted us to supply our
own implementation might have been fixed.  To use the system supplied
XDR, edit the `make.com' file and comment-out additions to the netCDF
library from the XDR directory (i.e. have it do nothing except build the
`xdrtest' program).  You'll have to remove any of our XDR object files
from the netCDF library if they've already been added.
