Update.
1999-03-08 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * sysdeps/unix/sysv/linux/ttyname.c (ttyname): Undo last change. /dev/pts status may change during runtime. 1999-03-08 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * sysdeps/unix/sysv/linux/ttyname_r.c (__ttyname_r): Undo last change. /dev/pts status can change during runtime. 1999-03-07 Thorsten Kukuk <kukuk@suse.de> * sunrpc/svc_tcp.c (readtcp): go into fatal error state if poll reports error. * nis/nss_nisplus/nisplus-parser.c: Avoid duplicate strlen calls, add some more sanity checks. * nis/nss_nisplus/nisplus-pwd.c: Include nisplus-parser.h for parser prototype. 1999-03-05 Thorsten Kukuk <kukuk@suse.de> * sunrpc/rpc/xdr.h: Add x_getint32/x_putint32 to xdr_ops, change XDR_GETINT32/XDR_PUTINT32 to sue new functions. * sunrpc/xdr_mem.c: Add xdrmem_getint32, xdrmem_putint32. * sunrpc/xdr_rec.c: Add xdrrec_getint32, xdrrec_putint32. * sunrpc/xdr_sizeof.c: Add x_putint32, add dummy function for x_getint32. * sunrpc/xdr_stdio.c: Add xdrstdio_getint32, xdrstdio_putint32. * nis/nis_print.c: Fix ctime argument for platforms where sizeof (time_t) != sizeof (int). 255. Patch by Bruno Haible <haible@ilog.fr> [PR libc/1010].
