 $Log: dynAnyImpl.h,v $
 Revision 1.1.2.3  2001/10/19 11:04:03  dpg1
 Avoid confusing (to gcc 2.95) inheritance of refcount functions.

 Revision 1.1.2.2  2001/10/17 18:51:51  dpg1
 Fix inevitable Windows problems.

 Revision 1.1.2.1  2001/10/17 16:44:05  dpg1
 Update DynAny to CORBA 2.5 spec, const Any exception extraction.

 Revision 1.1.2.1  2001/04/18 17:18:17  sll
 Big checkin with the brand new internal APIs.
 These files were relocated and scoped with the omni namespace.

 Revision 1.5.2.5  2000/11/17 19:09:37  dpg1
 Support codeset conversion in any.

 Revision 1.5.2.4  2000/11/09 12:27:53  dpg1
 Huge merge from omni3_develop, plus full long long from omni3_1_develop.

 Revision 1.5.2.3  2000/10/06 16:40:53  sll
 Changed to use cdrStream.

 Revision 1.5.2.2  2000/09/27 17:25:41  sll
 Changed include/omniORB3 to include/omniORB4.

 Revision 1.5.2.1  2000/07/17 10:35:41  sll
 Merged from omni3_develop the diff between omni3_0_0_pre3 and omni3_0_0.

 Revision 1.6  2000/07/13 15:26:02  dpg1
 Merge from omni3_develop for 3.0 release.

 Revision 1.2.8.3  1999/10/26 20:18:20  sll
 DynAny no longer do alias expansion on the typecode. In other words, all
 aliases in the typecode are preserved.

 Revision 1.2.8.2  1999/09/22 16:15:59  djr
 Removed MT locking.
