arguments.

DATA for the entry SP; DATA[-1] is always the return address
location. In both cthreads and non-cthreads cases, use asm to
force parameters into %eax and %ecx before return, and mutate
DATA[-1] to return to specific asm code to set up the user from
%eax and %ecx.
[PIC] (_init): Caller changed.
(__libc_init_first) [! PIC] (doinit): Use asm to effect call to init
with SP unwound to argument data ptr.

when 0x08000000 and up are not mapped.
* Makerules (stamp$o-$(subdir) rule): Remove the timestamp file
before touching it.
(lib%.so): Use -Wl to get -soname to ld.
* elf/dlsym.c: Pass final arg to _dl_lookup_symbol.
* elf/Makefile (libdl.so): Pass $(LDFLAGS.so).
from zero fill.
* elf/dl-lookup.c (_dl_lookup_symbol): Take new flag arg NOSELF;
if nonzero, don't let *REF satisfy the reference itself.
* elf/link.h (_dl_lookup_symbol): Add new arg NOSELF in decl.
* sysdeps/i386/dl-runtime.c (_dl_runtime_resolve): Pass new arg to
_dl_lookup_symbol.

satisfy the reference itself if its value equals the reloc's
offset.
* elf/rtld.c (dl_main): Write a newline in fatal msg.
* Makerules (lib%.so: lib%_pic.a): Pass $(LDFLAGS.so).
* elf/rtld.c [! NDEBUG] (__assert_perror_fail): New function.
* hurd/hurdstartup.c (_hurd_startup): Fancier kludge to guess phdr
and user entry point addresses.
* elf/dl-load.c (open_path): Don't do strlen on DIRPATH if it's null.
(_dl_map_object): DT_RPATH value is relative to DT_STRTAB value.
* Makerules (install-lib.so): Don't include libc.so.
[$(build-shared)=yes] (install): Depend on the installed libc.so file.
[$(build-shared)=yes] (install-no-libc.a): Make this, rather than
install, depend on the installed $(install-lib.so) files.
[$(build-shared)=yes] (install-lib.so): Append libc.so after that rule.

when successful.
* sysdeps/mach/hurd/dl-sysdep.c (threadvars): New static variable.
(__hurd_threadvar_max, __hurd_threadvar_stack_offset): Define these
variables, using the `threadvars' buffer.

* elf/rtld.c (dl_main): Add missing NULL terminating argument in
_dl_sysdep_fatal call.

lt_interpreter, first undo relocation done during bootstrapping.
* elf/elf.h (ELFMAG): Use \177 instead of \x7f. It seems GCC
insists on seeing the following E as part of hex 7FE, and
complaining that is wider than a byte.
* mach/Makefile (server-interfaces): Removed notify and
device_reply. For shlibs with eager binding, libmachuser.so must
not refer to any functions not defined in libc.
* Makeconfig (+gccwarn): Add -Winline.

set, avoid abort_rpcs, and use reply and intr ports saved in

from SS->context. Don't clear SS->context.
* sysdeps/mach/hurd/i386/sigreturn.c: Don't set SS->intr_port when

SS->context.
