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.

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. Mon Nov 18 05:51:13 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/waitstatus.h (__WIFSIGNALED): Rename local variable from __stat to __status to prevent shadowing. * sunrpc/rpc/clnt.h (clntudp_create, clntudp_bufcreate): Likewise for parameter __wait. 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. (routines): Add regexp.c. Update copyright. Sun Nov 17 21:50:24 1996 Andreas Jaeger <aj@arthur.pfalz.de> * stdlib/tst-strtod.c (main): Add arguments for main. * stdlib/tst-strtol.c (main): Likewise. Sun Nov 17 21:15:05 1996 Ulrich Drepper <drepper@cygnus.com> * configure.in: Substitute libc_cv_slibdir and libc_cv_sysconfdir in output files. * sysdepes/unix/sysv/linux/configure: Define libc_cv_slibdir to /lib and sysconfdir to /etc if $prefix is /usr. * config.make.in: Add slibdir, sysconfdir and BASH to be replaced. * elf/Makefile ($(objpfx)ldd): Install ldd.bash.in if $(have-bash2) is yes. * elf/ldd.bash.in: Add copyright and various cleanups. * elf/ldd.sh.in: Likewise. Implement RTLD_NEXT. * elf/dlfcn.h: Define RTLD_NEXT. * elf/dl-deps.c: Build second searchlist which contains duplicates. * elf/dl-lookup.c (_dl_lookup_symbol_skip): New function. Used for RTLD_NEXT lookup. Rewrite _dl_lookup_symbol to put common parts for both lookup functions in a separate function. * elf/dlsym.c: Handle RTLD_NEXT by calling _dl_lookup_symbol_skip. * elf/link.h (struct link_map): Add l_dupsearchlist and l_ndupsearchlist. Add prototype for _dl_lookup_symbol_skip. * sunrpc/Makefile (rpcsvc): Add rusers. * sunrpc/rpcsvc/rnusers.x: Remove. Obsolteted by rusers.x. * sunrpc/rpcsvc/rusers.x: New file.
