i'm writing on a programm which uses the boost date_time library [boost-version = 1.32.0] heavily; while i normally programm in linux using gcc-3.3.5 i also need to compile my program in windows from time to time. because it makes life easier with another library [gtkmm-2.4.8] i'm using mingw-3.4.2; everthing worked fine (my code contains about 10 000 lines using boost_date_time) until i started using a boost::gregorian::year_based_generator. while gcc-3.3.5 in liux accepts my code without even a single warning [with -Wall], mingw-3.4.2 complains - it seems that the compiler has problems with year_based_generator: calendar.hpp:60: error: variable or field `insertGenerator' declared void calendar.hpp:60: error: expected `;' before '(' token calendar.hpp:92: error: expected `)' before '*' token calendar.hpp:95: error: using-declaration for non-member at class scope calendar.hpp:95: error: expected `;' before '*' token here is the header: /* This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
