My memory is a bit fuzzy (isn't it always... ;-), but as I remember it, new-style syscall stub support is tied to NPTL, so vfork.S is never actually compiled when new-style syscalls stubs are in effect. Because of that, DO_CALL_VIA_BREAK isn't _necessary_ for vfork.S. Furthermore, the gas workarounds are needed only for the new-style syscall stubs. If you preferred them to be in sync, I _think_ it would be OK to make vfork.S more similar (perhaps even identical) to pt-vfork.S. --david
