in /usr/local/inclue/boost/system dir,for update  version:

[root_at_localhost system]# find ./ -type f -print|xargs grep "get_system_category" -n
./windows_error.hpp:110:        { return error_code( e, get_system_category() ); }
./cygwin_error.hpp:49:        { return error_code( e, get_system_category() ); }
./error_code.hpp:205:    BOOST_SYSTEM_DECL const error_category &  get_system_category();
./error_code.hpp:208:    static const error_category &  system_category = get_system_category();
./error_code.hpp:216:    static const error_category &  native_ecat    = get_system_category();
./error_code.hpp:315:      error_code() : m_val(0), m_cat(&get_system_category()) {}
./error_code.hpp:343:        m_cat = &get_system_category();
./linux_error.hpp:102:        { return error_code( e, get_system_category() ); }

not update from the old boost version.

[root_at_LOG system]#  find ./ -type f -print|xargs grep "get_system_category" -n
./error_code.hpp:211:    inline const error_category &  get_system_category() { return system_category(); }

which seems that when i update boost by ¡°bjam install¡±  ,the  /usr/local/inclue/boost/system/error_code.hpp not been overwrited,its still the older version.
