 *   Writing code that is portable between platforms with or without
 *   native C++ exceptions is hard.  The following macros offer some
 *   help on this task, mostly oriented to making the ORB code and the
 *   IDL generated code portable.

// The Windows MFC exception mechanism requires that a caught CException
// (including the CMemoryException in use here) be freed using its Delete()
// method. Thus, when MFC is in use and we're catching exceptions as a result
// of new(), the exception's Delete() method has to be called. No other
// platform imposes this sort of restriction/requirement. The Windows
// config stuff (at least for MSVC/MFC) defines a ACE_del_bad_alloc macro
// that works with its ACE_bad_alloc macro to implement this cleanup
// requirement. Since no other platform requires this, define it as
// empty here.
