4660	Error read binary archive, created  by old boost version	serge-voropaev@…	Robert Ramey	"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.
