* 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].
* elf/dl-minimal.c (malloc): Conditionalize use of _dl_zerofd
on [! MAP_ANON].
* elf/rtld.c (dl_main): Likewise.
* elf/dl-load.c (_dl_zerofd): Conditionalize defn on [! MAP_ANON].
(_dl_map_object_from_fd): Conditionalize initialization of _dl_zerofd.
* elf/dl-fini.c (_dl_fini): Skip finalizer for executable itself.
Sat Jul 13 02:47:53 1996 David Mosberger-Tang <davidm@azstarnet.com>
* stdlib/random.c (__random): Declare as int32_t to be in sync
with declaration.
* socket/Makefile (headers): Add socketbits.h.
* misc/mntent.c (endmntent): Allow for NULL stream. SunOS does
it that way.
* grp/initgroups.c (initgroups): Add groups that user is a member
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.
* sysdeps/unix/getlogin.c (getlogin): Initialize ut_fd with -1.
Thu Jul 11 16:59:10 1996 David Mosberger-Tang <davidm@azstarnet.com>
* misc/mntent.c (addmntent): Seek to end of file before writing
entry. Return 1 on error, not -1.
Tue Jul 9 19:08:05 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/syscalls.list: Mark bdflush as EXTRA
syscall.
Fri Jul 5 18:44:55 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/alpha/ioperm.c (port_to_cpu_addr): Size
shift amount for Jensen must be 5 not 4.
Sat Jul 13 20:04:28 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* socket/sys/socket.h (struct osockaddr): New type.
Sat Jul 13 03:50:53 1996 Ulrich Drepper <drepper@cygnus.com>
* misc/Makefile (routines): Add qefgcvt and qefgcvt_r.
* 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'
versions.
* stdlib/stdlib.h: Add prototypes for q[efg]cvt() and q[ef]cvt_r()
functions.
* manual/startup.texi: Document new getsubopt function.
* manual/examples/subopt.c: New example program for documenting
getsubopt function.
Fri Jul 12 23:58:37 1996 Ulrich Drepper <drepper@cygnus.com>
* stdlib/Makefile (routines): Add getsubopt.
* stdlib/stdlib.h: Add prototype for getsubopt.
* stdlib/getsubopt.c: New file. Implement getsubopt function
to handle suboption parsing.
