Yes, there was a non-standard use of the "friend" qualifier in the C++
code (it tried to declare a constructor a friend, but friend can only
be used with a Class's methods and a constructor is not really a
method).  We fixed the problem in netcdf-3.5beta8, which you could
try.  Just get it from 

  ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.5-beta8.tar.Z

Or if you just want to fix the code in version 3.4, you can use the
appended patch to netcdf.hh, which is now named netcdfcpp.h
