Could you elaborate on how you measure that? With musl only the parts of stdio you actually use will be linked, and use of exit does not result in linking of any additional code, since the startup code has to call exit(main(...)) anyway. In any case exit and its dependencies are tiny. Rich _______________________________________________ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
