Wed Nov 20 02:04:11 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/sigsuspend.c: Make sigsuspend a weak alias of __sigsuspend. * grp/grp.h: Correct comment about POSIX compliance. * pwd/pwd.h: Likewise. * login/utmp.h: Update copyright and pretty-print prototypes. * sysdeps/generic/paths.h: Add _PATH_LASTLOG, _PATH_UTMP and _PATH_WTMP from utmpbits.h. * sysdeps/unix/sysv/linux/paths.h: Likewise. * sysdeps/generic/utmpbits.h: Remove here. * sysdeps/gnu/utmpbits.h: Likewise. * misc/sys/uio.h: Place __BEGIN_DECLS correctly. Pretty-print prototypes. * sysdeps/unix/sysv/linux/sparc/clone.S: New file. Taken from LinuxThreads-0.5. Tue Nov 19 13:43:07 1996 Richard Henderson <rth@tamu.edu> * inet/ether_hton.c: Include <string.h>. * inet/ether_ntoh.c: Likewise. * inet/rexec.c: Get errno, index, getpass, getlogin from headers. * misc/search.h: Fix hcreate_r argument type (unsigned -> size_t). * misc/sys/cdefs.h: Change __long_double_t definition from typedef to define.

Reported by Eric Youngdale. While we're at this, don't do error checking in the __ functions. This is consistent with the sysv4 definitions and seems Right. * signal/signal.h: Don't __OPTIMIZE__ sigops to __ versions. Add prototype for __sigsuspend. * sysdeps/posix/sigblock.c: Optimize sigmask <-> sigset_t conversions for sigset_t == unsigned long. De-ansidecl-ify. Reformat copyright. * sysdeps/posix/sigpause.c: Likewise. * sysdeps/posix/sigsetmask.c: Likewise. * sysdeps/posix/sigvec.c: Likewise. * sysdeps/posix/sigintr.c: Reformat copyright. * sysdeps/posix/signal.c: Check signal number out of range since __sigismember doesn't anymore. Reformat copyright. * sysdeps/posix/sigwait.c: Use __ versions of sigfillset, sigismember, sigdelset, sigaction, and sigsuspend. * stdlib/drand48-iter.c (__drand48_iterate): Cast state fragments to the wider type before shifting. * sysdeps/alpha/bsd-_setjmp.S: Silence assembler warning "$at used without .set noat" in profiling hook. * sysdeps/alpha/bsd-setjmp.S: Likewise. * sysdeps/alpha/htonl.S: Likewise. * sysdeps/alpha/htons.S: Likewise. * sysdeps/alpha/s_copysign.S: Likewise. * sysdeps/alpha/setjmp.S: Likewise. * sysdeps/alpha/stpcpy.S: Likewise. * sysdeps/alpha/strcat.S: Likewise. * sysdeps/alpha/strcpy.S: Likewise. * sysdeps/alpha/strncat.S: Likewise. * sysdeps/unix/sysv/linux/alpha/brk.S: Likewise. * sysdeps/unix/sysv/linux/alpha/clone.S: Likewise. * sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S: Likewise. * sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S: Likewise. * sysdeps/unix/sysv/linux/alpha/llseek.S: Likewise. * sysdeps/unix/sysv/linux/alpha/sigsuspend.S: Likewise. Rename function to __sigsuspend and add weak alias. * sysdeps/unix/sysv/linux/alpha/syscall.S: Likewise. Add missing END. * sysdeps/alpha/w_sqrt.S: Define _ERRNO_H so <errnos.h> defines EDOM. * sysdeps/unix/execve.S: Match PSEUDO_END symbol with the symbol SYSCALL__ actually generated. * sysdeps/unix/sysv/linux/errnos.h [_LIBC_REENTRANT]: Reflexively #define __set_errno, as several imported subsystems (eg. BIND) check that the symbol is defined. * sysdeps/unix/sysv/linux/getsysstats.c: Include <alloca.h>. * sysdeps/alpha/memcpy.S: Temporarily remove until I can find a bug that manifests in GCC. Tue Nov 19 11:10:05 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * sysdeps/posix/writev.c (writev): COUNT parm is now int. * sysdeps/posix/readv.c (readv): Likewise. Tue Nov 19 15:28:29 1996 Ulrich Drepper <drepper@cygnus.com> * nss/nss_dns/dns-network.c: Change return type of all functions to enum nss_status. Reported by NIIBE Yutaka. * nss/nss_dns/dns-host.c: Update copyright. Fri Nov 15 20:16:38 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * config.make.in: Remove definition of top_absdir. * configure.in: Likewise. Use $(..) instead. * Makerules (make-link): Use $(..) to find rellns-sh script. Sat Nov 16 15:52:29 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * manual/nss.texi (Name Service Switch): Fix reference to `frobnicate'. Fri Nov 15 22:08:33 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Add sys/mtio.h.

Reported by NIIBE Yutaka. Mon Nov 18 02:05:38 1996 Ulrich Drepper <drepper@cygnus.com> * misc/regexp.c: New file. Implementation of obsolete interface to regular expression matcher (required in XPG4.2). * misc/regexp.h: New file. Header for above. * misc/Makefile (headers): Add regexp.h.
