/* 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!
