>Description:
	When creating a class with in it an union, not all exports come in
the object file 
>How-To-Repeat:
when compiling the following code with 
g++ -DWITH_BUG=1 -c BugDemo.cpp 
the generated object file will not contain exports
when compiling with
g++ -DWITH_BUG=0 -c BugDemo.cpp 
the generated object file will contain exports
/*** Start of code ***/
// BugDemo.cpp: demonstration of export bug

class __declspec (dllexport) BugDemo

	virtual ~BugDemo();
	union
	{
#if WITH_BUG
	    class BugDemo*	m_pBugDemo;
#else		    
   		BugDemo*	m_pBugDemo;
#endif
