Good morning! I have a line of code as follows (excuse erroneous capitulation, it's my mailer) XtPointer client_data; // which is really void * u_int days = reinterpret_cast<u_int>(client_data); When I compile with gcc-4.1.2 I get: error: cast from 'void*' to 'u_int' looses precision This is the first time I've tried to rebuild this program with gcc-4, it was previously build with gcc-2.95.2 (really old code but it works and is simple). What am I missing here??? Thanks! -b
