%eax and %ecx.
[PIC] (_init): Caller changed.

installation rules.
* sysdeps/mach/sysdep.h [HAVE_ELF] (ENTRY): Redefine this macro so
it uses the `.type' directive, which is necessary for shared
libraries to work properly.

satisfy the reference itself if its value equals the reloc's
offset.

lt_interpreter, first undo relocation done during bootstrapping.

device_reply. For shlibs with eager binding, libmachuser.so must
not refer to any functions not defined in libc.

args on stack from kernel.

in the absence of CVS dirs.
* hurd/hurdstartup.c: Don't call __mach_init. Grok args from the

update.
(config.status): New target; depend on configure.
If target (config.status) exists, run it with --recheck to update;
if not, give error msg saying to run confiugre by hand.

(sysd-Makefile-force): Set this variable to FORCE in this case, to
force a rebuild of sysd-Makefile.

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

properly, and deal with a send right dying while we try to copy

failures.
