Milestone:  To Be Determined          |   Component:  serialization
  Version:  Boost 1.44.0              |    Severity:  Showstopper

 I have some binary archive files, which was created by old version of
 boost::serialization. New (1.44) version does not read these files.
 Program throws exception “unsupported_version”

 I have done some small investigation. The pproblem is:

 Old code writes library_version as 1 byte, but new code (1.44)  writes
 library_version as unsigned short!!!

 You can see in attachment  2 files, which was created
 boost_1_44_0\libs\serialization\example\demo.cpp. I modify this program
 for work with binary archive. First file demofile.dat was created with
 boost 1.43. Second file demofile_1_44.dat. Was created with boost 1.44.

 I think it is very serious bug, as archive compatibility was ruined.
