For netCDF 3.4, I've deleted the #include <generic.h> in cxx/netcdf.hh
and inserted the following definitions at about line 49 in
that file:

// macros to glue tokens together to form new names (used to be in generic.h)
#define name2(a,b) a ## b
#define declare(clas,t)        name2(clas,declare)(t)
#define implement(clas,t)      name2(clas,implement)(t)

I think that should fix things for gcc 2.8.0, but we haven't got around
to building and installing it here for testing yet.

Also, we have an alpha test version of netcdf 3.4 that already includes
this change among others, available from

  ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.4a.tar.Z

in case you'd like to try it.

Thanks for reporting the problem, and please let me know if either of
the above two suggestions doesn't fix it.
