/**
 * Export interfaces for library interfaces.
 * This is a special header used when we have to build DLL's for dumb
 * platforms which require explicit declaration of imports and exports.
 * The real purpose is to include our local headers in a new library
 * module with external headers referenced as imports, and then to define
 * our own interfaces in our new library as exports.  This allows native
 * construction of new DLL's based on/that use ucommon on Microsoft Windows
 * and perhaps for other similarly defective legacy platforms.  Otherwise
 * this header is not used at all, and not when building applications.
 * @file ucommon/export.h
