Problem with variadic macros, Forte 6U2

Question

The following code demonstrates a problem with namespace qualifiers used in variadic macros. The workaround (if you want to call it that) is to use triple colons as the scope resolution operator inside certain cases of variadic macros. The following piece of very contrived code demonstrates the problem. If you look at preproccessed output, its pretty clear that the variadic macro eats colons.

#define EXTENDS(...) __VA_ARGS__

}//namespace bar
}//namespace foo
#if !defined(HACK_TO_FIX)
   class DerivedInterface : EXTENDS( INTERFACE(::foo::bar::Interface) )
#else
   class DerivedInterface : EXTENDS( INTERFACE(:::foo:::bar:::Interface) )  
#endif

OK - that is good to hear. OTOH, I think I've found another one. The following code builds properly whether or not DEFINE_IN_CLASS_BODY is set on both g++ 3.0.1 and on the online comeau C++ compiler. However, in Forte 6U2, if DEFINE_IN_CLASS_BODY is not set, compilation fails.
unix experiments/C++/over_template> cat over_template.cpp
#if defined(DEFINE_IN_CLASS_BODY)
class Factory {
public:
   void * create() const {
      return new int;
   template<typename T> T * create() const {
      return reinterpret_cast<T*>(create());
#else
class Factory {
public:
   void * create() const;
   template<typename T> T * create() const;
inline void * Factory::create() const {
   return new int;
template<typename T> inline T * Factory::create() const {
   return reinterpret_cast<T*>(create());
#endif
int main(int argc, char * argv[]){}unix experiments/C++/over_template> \rm -rf SunWS_cache/; CC over_template.cpp

This last compile works fine. Using Forte6U2, all the latest patches installed.
