Hi! Can anyone tell me why the compilation of the program which uses Boost.Date_Time (boost ver. 1.33) displays 3 warnings: /usr/include/boost/date_time/time_facet.hpp:202: warning: unused parameter 'a_ref' /usr/include/boost/date_time/time.hpp:81: warning: unused parameter 'as_offset' /usr/include/boost/date_time/time.hpp:88: warning: unused parameter 'as_offset' I know this are just warnings, but why they appears? Are that wariables really unused? :-). Best regards. -- |\/\/|   Seweryn Habdank-Wojewódzki `\/\/'
