* $Log: exceptions.hpp,v $
* Revision 1000.1  2004/06/01 19:39:22  gouriano
* PRODUCTION: UPGRADED [GCC34_MSVC7] Dev-tree R1.9
*
* Revision 1.9  2004/05/12 18:33:23  gouriano
* Added type conversion check (when using _type DEF file directive)
*
* Revision 1.8  2004/04/30 11:27:14  kuznets
* Use THROWS macro to specify exceptions
*
* Revision 1.7  2003/03/10 18:53:15  gouriano
* use new structured exceptions (based on CException)
*
* Revision 1.6  2000/04/07 19:26:08  vasilche
* Added namespace support to datatool.
* By default with argument -oR datatool will generate objects in namespace
* NCBI_NS_NCBI::objects (aka ncbi::objects).
* Datatool's classes also moved to NCBI namespace.
*
* Revision 1.5  2000/03/16 17:43:54  vasilche
* Added missing forward declaration.
*
* Revision 1.4  2000/03/16 17:41:13  vasilche
* Missing USING_NCBI_SCOPE
*
* Revision 1.3  2000/03/16 17:27:02  vasilche
* Added missing include <stdexcept>
*
* Revision 1.2  2000/03/15 21:23:59  vasilche
* Error diagnostic about ambiguous types made more clear.
*
* Revision 1.1  2000/02/01 21:46:17  vasilche
* Added CGeneratedChoiceTypeInfo for generated choice classes.
* Removed CMemberInfo subclasses.
* Added support for DEFAULT/OPTIONAL members.
* Changed class generation.
* Moved datatool headers to include/internal/serial/tool.
*
* Revision 1.3  1999/11/15 19:36:14  vasilche
* Fixed warnings on GCC
