   /* With the exception of WORD, the IBM Visual Age C++ compiler has
      its own definitions of the Harbour types defined in the #else
      section of this #ifdef block, most of which conflict with the
      Harbour #undefs, due to typedef being the prevalent method of
      defining the types in IBMCPP, whereas Harbour assumes that the
      definitions that it is replacing have been defined using
      #define. Therefore, it is necessary to skip the Harbour
      definition section when using the IBMCPP compiiler, include
      the IBMCPP type definitions, and then add the definition for WORD

      NOTE: This only applies to the common types that most C compilers
            define. Any new types, particulary those that start with
            HB_, must be placed AFTER the #endif __IBMCPP__ line!
