the reason of the presence of such a flag is that the optimized program is generally less 'debug-able' because the instructions that you type in your C++ program are compiled with less fidelity but more performance in mind (still 'doing the same thing') HIH Armel _______________________________________________ help-gplusplus mailing list help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
