1998-09-28 23:55 Ulrich Drepper <drepper@cygnus.com> * nis/ypclnt.c (__yp_bind): Pretty print. Optimize readv result check a bit. Also close socket of domain client. Close socket in IPPORT_RESERVED error case. 1998-09-28 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/bits/socket.h (__cmsg_nxthdr): Use CMSG_ALIGN (fixes a bug) and correct test for availability of another entry. * sysdeps/unix/sysv/linux/mips/bits/socket.h: Sync with generic Linux version. (__cmsg_nxthdr): Use CMSG_ALIGN (fixes a bug) and correct test for availability of another entry. Patch by ak@muc.de. * sysdeps/unix/sysv/linux/netinet/ip.h (IPOPT_NOOP): Fix typo. Patch by ak@muc.de. 1998-09-27 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * posix/annexc.c (xsystem): New function. Use it instead of system. 1998-09-28 Ulrich Drepper <drepper@cygnus.com> * stdlib/longlong.h: Remove #endif for #if removed in last change.
