Update.
* elf/Versions [libc, GLIBC_2.01]: Add _dl_global_scope_alloc. * elf/dl-open.c (_dl_global_scope_alloc): Move definition to * elf/dl-deps.c: ...here. * elf/dl-open.c (dl_open_worker): Call _dl_map_object_deps with new parameter and expect result. Remove code handling RTLD_GLOBAL. Add return value of _dl_map_object_deps to _dl_main_searchlist->r_nlist. * elf/dl-deps.c (_dl_map_object_deps): Change to return value. If we parameter GLOBAL is nonzero add object and dependencies to the global scope. * elf/ldsodefs.h: Adapt prototype for _dl_map_object_deps. * elf/rtld.c (dl_main): Call _dl_map_object_deps with new parameter. Mark all objects as in global scope. * elf/dl-object.c (_dl_new_object): Initialize l_global to zero. * sysdeps/unix/sysv/linux/bits/sockunion.h: Add Econet support. * sysdeps/unix/sysv/linux/i386/sysdep.h: Add .L prefix to symbols used in macro magic. 1998-11-02 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/unix/sysv/linux/netatalk/at.h: Include <linux/atalk.h> before <sys/socket.h> to make sockaddr_at available to <sys/socket.h>. * posix/glob.h: Remove __P from parameter lists of declarations. 1998-11-02 Andreas Jaeger <aj@arthur.rhein-neckar.de> * time/tzset.c (tz_compute): Remove unused parameter timer. Change caller. 1998-11-02 Mark Kettenis <kettenis@phys.uva.nl> * sysdeps/generic/bits/types.h (__ipc_pid_t): New typedef. 1998-11-02 Ulrich Drepper <drepper@cygnus.com>
