Sorry I didn't explain that it's necessary to rebuild netCDF from the
`configure' step after the patches.

You need to remake netCDF after applying patches 3 and 4 before trying to
build from the C++ sources.  One of the things patch3 does is delete some
typedefs from netcdf/libsrc/netcdf.h.in that should not be there and that
conflict with a C++ typedef:

    typedef char        ncchar;
    typedef char        ncbyte;
    typedef short       ncshort;
    typedef float       ncfloat;
    typedef double      ncdouble;

(Only the 'nclong' typedef should remain.)

After applying patch3 that deletes these typedefs (and then patch4), it's
necessary to rebuild from scratch, because `netcdf.h' gets created from
`netcdf.h.in' during the running of the `configure' script.  If you have the
`config.status' script lying around from after you ran `configure' it would
suffice to run that, since that will create a new `netcdf.h' from
`netcdf.h.in'.

Then once the `make all' and `make test' steps show you have a working
netCDF library (`make install' is optional at this point), change to the C++
directory and try again.

Unfortunately I haven't been able to install a recent g++ compiler here
because of disk problems with our GNU sources, so it may be a week or so
before I can verify that the patch-level-4 version works with g++ version
2.6.3 or find out what problems remain.  I know that the patch-level-4
version works OK with several other C++ compilers on various platforms.

However it looks to me like the other error messages you are seeing result
from the conflicting `typedef char ncbyte' in netcdf.h and `typedef unsigned
char ncbyte' in netcdf.hh that patch 3 followed by a rebuild is supposed to
fix.

Thanks Russ!  Installed without problem.

I'm having Dan Kelley test it for me now.
