Ok. I switched my SWIG interface to the following so that
BUILD_SHARED_WIN32 and dted_EXPORTS were defined. That clears the
syntax error message and gives me a todo list of warnings I need to
wrap or ignore.

%module My_Interface
%{
#include "dted/longitude.hpp"
%}

%include "windows.i"

/// Trying to rename the less than operator in the dted::units namespace
%rename(LonLessThan) operator< ( Longitude const& , Longitude const& );

#define BUILD_SHARED_WIN32
#define dted_EXPORTS
%include "dted/dll_defines.hpp"
%include "dted/longitude.hpp"

I will run with this and if I come across a problem I will reply.
Thanks for the help. I am feeling more confident about using SWIG.
