r_duplist is not anymore allocated separately. l_initfini is and
therefore free it if necessary.
* elf/dl-deps.c: If a searchlist has to be allocated, put all in one
malloc block. Otherwise allocate l_initfini list only.
Put dependencies for the object in l_initfini list.
Sort dependencies for the object to be loaded topologically.
* elf/dl-fini.c: Before running the destructors sort the topologically.
* elf/dl-init.c (_dl_init): Renamed from _dl_init_next. Rewrite to

effect for shared objects. Don't emit message and call only for
static library.

as nonzero in case the buffer passed in at runtime is unaligned with
respect to the character set encoding involved.

variable.

* posix/unistd.h (intptr_t): Conditionalize on [__USE_MISC ||
__USE_XOPEN_EXTENDED] rather than on [__USE_UNIX98].

strings with %Zu, because gcc-2.95.2's -Wformat knows about the latter
but not the former.
2000-03-19 Ulrich Drepper <drepper@redhat.com>
* sysdeps/generic/glob.c [_LIBC]: Always use __xstat64, not only for
glob64. Since there is no glob64 in the LFS proposal applications
can assume that glob handles LFS situations. glob64 is only needed
if alternative filesystem functions are used.
2000-03-19 Geoff Clare <gwc@unisoft.com>
* sysdeps/generic/glob.c: Correct gl_pathc value returned

[$(versioning) = yes] (before-compile): Prepend abi-versions.h.

(__flockfile, __funlockfile, __ftrylockfile): Functions renamed
from __internal_*.
(flockfile, _IO_flockfile, funlockfile, _IO_funlockfile,
ftrylockfile, _IO_ftrylockfile): Fix aliases accordingly.
* sysdeps/generic/bits/stdio-lock.h (_IO_lock_initializer): Use ...
for more pleasing parse error.

2000-03-04 Ulrich Drepper <drepper@redhat.com>
* posix/wordexp-test.c: Correct one of the tests added in the last
change. Really get the root passwd entry to check again ~root.
(input, output): Functions removed.
(mach_open_devstream): Use devstream_{read,write} as cookie functions,
using only the vanilla fopencookie interface.

as macro for __io_functions.
(funcsio): Use cookie_io_functions_t type name.

to be a pointer, in line with the manual and the old stdio.
* libio/iofopncook.c (_IO_cookie_seek): Fix (sole) caller.
* sysdeps/generic/bits/stdio-lock.h: New file.

sed regexp so as not to break directory names including /../ within.
* sysdeps/unix/bsd/bits/waitflags.h: File removed.
The sysdeps/generic file is right for BSD. This file was in fact the
Hurd file, but the only difference was the WNOREAP flag that was never
actually implemented or used anywhere.
since AC_PATH_PROG already does it for us.
(PERL): Rewrite check added in 2000-02-29 change for syntactic
correctness and sh portability. I replaced the broken check
with a more sensible implementation of the apparently intended
semantics, which might still be questionable. Using expr causes
a non-numeric value for `perl -V:apiversion` to be accepted,
refusing to use only a perl that reports a number less than 5;
on my system, perl (5.004_04) -V:apiversion produces UNKNOWN.
