These files are taken from netcdf 4.0.

The source files are taken from the libsrc and include directories and
only contain the code needed to support the classic netcdf3 format.

The source files have been slightly modified in order to fit them into this
build system. The changes that were made are:

 - netcdf.h, ncx.h, and utf8proc.h include harp_netcdf_mangle.h to name mangle
   all public symbols.

 - Added several casts to unsigned to eliminate 'comparison between signed
   and unsigned' warnings.

 - Added '(void)variable;' entries in many functions to eliminate
  'unused parameter' warnings.

 - Added missing initializer values to utf8proc_properties in
   utf8proc_data.h.
