Update.
1999-05-26 Ulrich Drepper <drepper@cygnus.com> * config.h.in: Add __LINUX_KERNEL_VERSION. * configure.in: Recognize --enable-kernel. * sysdeps/unix/sysv/linux/configure.in: Check for correct kernel headers if --enable-kernel is given and set __LINUX_KERNEL_VERSION appropriately. * sysdeps/unix/sysv/linux/init-first.c: If minimal kernel version is given perform runtime test. * sysdeps/unix/sysv/linux/kernel-features.h: New file. * sysdeps/unix/sysv/linux/getcwd.c: Elide compatibility code if minimal supported kernel is known to have the feature. * sysdeps/unix/sysv/linux/poll.c: Likewise. * sysdeps/unix/sysv/linux/pread.c: Likewise. * sysdeps/unix/sysv/linux/pread64.c: Likewise. * sysdeps/unix/sysv/linux/pwrite.c: Likewise. * sysdeps/unix/sysv/linux/pwrite64.c: Likewise. * sysdeps/unix/sysv/linux/seteuid.c: Likewise. * sysdeps/unix/sysv/linux/sigaction.c: Likewise. * sysdeps/unix/sysv/linux/sigprocmask.c: Likewise. * sysdeps/unix/sysv/linux/sigsuspend.c: Likewise. * sysdeps/unix/sysv/linux/testrtsig.h: Likewise. * sysdeps/unix/sysv/linux/i386/chown.c: Likewise. * sysdeps/unix/sysv/linux/i386/pread.c: Likewise. * sysdeps/unix/sysv/linux/i386/pread64.c: Likewise. * sysdeps/unix/sysv/linux/i386/pwrite.c: Likewise. * sysdeps/unix/sysv/linux/i386/pwrite64.c: Likewise. * sysdeps/unix/sysv/linux/sysctl.c: Add __sysctl alias.
