Initialization of the classes and implicitly used sysutils unit uses more code. Also the use of resourcestrings increases the binary. The size is mainly a rtl issue. The smartlinking principle in the compiler isn't changed since 1.0.6. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
