* manual/Makefile (glibc-targets): Variable and targets removed.

Sat Jul 13 23:50:17 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* manual/Makefile (lib): New phony target.  Depend on stamp files.
	($(objpfx)stamp%-$(subdir)): New rule to create them when necessary.

1996-07-13  Paul Eggert  <eggert@twinsun.com>

	* time/strftime.c (strftime): Use space padding for %e, %k, %l,
	to match Emacs format-time-string specification.
	(DO_NUMBER_SPACEPAD): Renamed from DO_NUMBER_NOPAD.

Sat Jul 13 20:17:38 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* elf/dl-deps.c (_dl_map_object_deps): Take new args PRELOADS and
	NPRELOADS, vector of `struct link_map *'s; add them to the searchlist
	between MAP and its deps.
	* elf/link.h: Fix decl.
	* elf/rtld.c (dl_main): If not secure, parse LD_PRELOAD for
	colon-separated list of names, map those and pass vector of ptrs as
	PRELOADS list to _dl_map_object_deps.
	* elf/dl-runtime.c (_dl_object_relocation_scope): Pass new args to
	_dl_map_object_deps with empty preload list.
	* elf/dl-open.c (_dl_open): Likewise.

	* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_open_zero_fill): Function
	removed.
	(__mmap): Pass MACH_PORT_NULL for memobj port when (flags & MAP_ANON).
	* sysdeps/generic/dl-sysdep.c (_dl_sysdep_open_zero_fill):
	Conditionalize defn on [! MAP_ANON].

Sat Jul 13 02:47:53 1996  David Mosberger-Tang  <davidm@azstarnet.com>

	with declaration.

	* socket/Makefile (headers): Add socketbits.h.

	* misc/mntent.c (endmntent): Allow for NULL stream.  SunOS does

 	of, not the ones he is _not_ a member of.

	* nss/nsswitch.c (known_compare): Make known_compare() a static
 	instead of a local function.  The latter are difficult to debug
 	and slow to execute on certain platforms.

	* sysdeps/posix/ttyname_r.c (ttyname_r): Use sizeof (dev) - 1 in
 	place of sizeof (dev).  The size of a literal string includes the
 	NUL byte.

	* misc/efgcvt.c, misc/efgcvt_r.c: Change code so that the `double'
	and `long double' versions can be generated.
	* misc/qefgcvt.c, misc/qefgcvt_r.c: New files.  Define macros
	so that included efgcvt{,_r}.c file generate `long double'

	functions.

	* manual/startup.texi: Document new getsubopt function.

+@subsection Parsing of Suboptions
+
+Having a single level of options is sometimes not enough.  There might
+be too many options which have to be available or a set of options is
+closely related.
+
+For this case some programs use suboptions.  One of the most prominent
+programs is certainly @code{mount}(8).  The @code{-o} option take one
+argument which itself is a comma separated list of options.  To ease the
+programming of code like this the function @code{getsubopt} is
+available.
+
+@comment stdlib.h
+@deftypefun int getsubopt (char **@var{optionp}, const char* const *@var{tokens}, char **@var{valuep})
+
+The @var{optionp} parameter must be a pointer to a variable containing
+the address of the string to process.  When the function returns the
+reference is updated to point to the next suboption or to the
+terminating @samp{\0} character if there is no more suboption available.
+
+The @var{tokens} parameter references an array of strings containing the
+known suboptions.  All strings must be @samp{\0} terminated and to mark
+the end a null pointer must be stored.  When @code{getsubopt} finds a
+possible legal suboption it compares it with all strings available in
+the @var{tokens} array and returns the index in the string as the
+indicator.
+
+In case the suboption has an associated value introduced by a @samp{=}
+character, a pointer to the value is returned in @var{valuep}.  The
+string is @samp{\0} terminated.  If no argument is available
+@var{valuep} is set to the null pointer.  By doing this the caller can
+check whether a necessary value is given or whether no unexpected value
+is present.
+
+In case the next suboption in the string is not mentioned in the
+@var{tokens} array the starting address of the suboption including a
+possible value is returned in @var{valuep} and the return value of the
+function is @samp{-1}.
