/* 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!
