Update.
1999-01-13 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/syscalls.list: Add __syscall_fork alias. * sysdeps/unix/sysv/linux/vfork.c: Use vfork syscall if available, otherwise use fork. * sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add vfork. * sysdeps/unix/sysv/linux/sparc32/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h: Correct handling of INLINE_SYSCALL for syscall without parameters.
