These errors in compiling the C++ interface are due to problems with
netCDF 3.5.0 complying to earlier versions of C++ compilers and
standards.  netCDF 3.5.1beta10 has been updated to comply with the
current C++ standard:

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

Unfortunately, the patches for 3.5.0 may not work with this newer
version.  At your convenience, please try the above beta test version
without any patches for the Intel 7.1 compilers and let us know
whether it works.

Alternatively, if you don't need the C++ interface, you could just
set the environment variable CXX='' before running the configure
script in version 3.5.0 to indicate that the C++ interface should not
be built ...

The 3.5.1-beta10 release has been tested with the latest gcc 3.x
compilers.
