Functions
static void	InternalAssert (const TCHAR AssertDescription, const char lpszFileName, INT32 nLine, BOOL UseMFC)
void	EnsureFailedLine (const TCHAR AssertDescription, const char lpszFileName, INT32 nLine)
	This macro is similar to the ASSERT macro, the only difference being that a description is provided of why the failure occured. The symbol _ENSURES is defined if the ENSURE macro expands to something, else is undefined if the ENSURE macro has no effect. IMPORTANT NOTE: ENSURE is obsolete. Use ERROR2xx or ERROR3xx macros instead.
void AFXAPI	AfxAssertFailedLine (LPCSTR lpszFileName, INT32 nLine)
	This is a more robust version than MFC provides.
