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.
