* Revision 1000.1  2004/06/01 19:41:43  gouriano
* PRODUCTION: UPGRADED [GCC34_MSVC7] Dev-tree R1.6
*
* Revision 1.6  2004/05/17 21:03:03  gorelenk
* Added include of PCH ncbi_pch.hpp
*
* Revision 1.5  2002/10/25 15:15:54  vasilche
* Fixed check for NCBI C toolkit.
*
* Revision 1.4  2002/10/25 15:05:44  vasilche
* Moved more code to libxcser library.
*
* Revision 1.3  2000/10/13 16:28:40  vasilche
* Reduced header dependency.
* Avoid use of templates with virtual methods.
* Reduced amount of different maps used.
* All this lead to smaller compiled code size (libraries and programs).
*
* Revision 1.2  1999/11/22 21:29:27  vasilche
* Fixed compilation on Windows
*
* Revision 1.1  1999/11/22 21:04:42  vasilche
* Cleaned main interface headers. Now generated files should include serial/serialimpl.hpp and user code should include serial/serial.hpp which became might lighter.
*
* Revision 1.3  1999/06/04 20:51:49  vasilche
* First compilable version of serialization.
*
* Revision 1.2  1999/05/19 19:56:57  vasilche
* Commit just in case.
*
* Revision 1.1  1999/03/25 19:12:04  vasilche
* Beginning of serialization library.
