Update.
1998-11-02 16:12 -0500 Zack Weinberg <zack@rabi.phys.columbia.edu> * sysdeps/generic/bits/signum.h: Define signals with their historical numbers when those are in the 1-15 range and consistent across platforms. Define compatibility aliases (SIGIOT, SIGCLD) if __USE_MISC. Define SIG_DFL, SIG_IGN, SIG_ERR as numeric constants cast appropriately instead of with fake function declarations (would cause link errors). If __USE_UNIX98, define SIG_HOLD. 1998-10-29 H.J. Lu <hjl@gnu.org> * sysdeps/unix/sysv/linux/bits/sigaction.h (sigaction): Use union only if __USE_POSIX199309 is defined. * misc/sys/select.h (pselect): Declared only if __USE_GNU is defined. * sysdeps/unix/sysv/linux/netatalk/at.h: Include <linux/atalk.h> before <sys/socket.h> to make sockaddr_at available to <sys/socket.h>.
