* sysdeps/unix/i386/sysdep.h (JUMPTARGET): New macro; use name@PLT
#ifdef PIC.
(PSEUDO): Use JUMPTARGET(syscall_error) in jump insn.
* sysdeps/unix/i386/syscall.S: Use JUMPTARGET(syscall_error) in
jump insn.
* sysdeps/unix/sysv/sysv4/linux/i386/sysdep.h: Rewritten.
* sysdeps/unix/sysv/sysv4/linux/i386/syscall.S: New file.
* sysdeps/unix/sysv/sysv4/linux/i386/socket.S: Include
<sys/socketcall.h>. Save %ebx in call-clobbered %edx instead of
stack. Use JUMPTARGET(syscall_error) in jump insn.
* Makeconfig (+gccwarn): Add -Wbad-function-cast -Wconversion.
* sysdeps/unix/i386/sysdep.h (ENTRY): Use ASM_GLOBAL_DIRECTIVE and
ASM_TYPE_DIRECTIVE.
(ASM_TYPE_DIRECTIVE): New macro; defined using `.type' #ifdef ELF.
* sysdeps/unix/sysv/sysv4/linux/i386/sysdep.S (__syscall_error):
Rewritten, #include'ing unix/i386/sysdep.S for most of the code.
* sysdeps/unix/i386/sysdep.S [PIC]: Store into `errno' through the GOT.
Fixes to help Linux, inspired by drepper's work:
* configure.in (os=linux*): Use unix/sysv/sysv4 for $base_os,
instead of unix/sysv.
* sysdeps/posix/utimes.c: New file.
* sysdeps/generic/getdomain.c: New file.
* sysdeps/i386/init-first.c: Removed gratuitous #include <hurd.h>.
* sysdeps/generic/dl-sysdep.c: Include <unistd.h> and declare
externals _dl_argc, _dl_argc, and _environ.
* sysdeps/unix/sysv/linux/{accept,connect,getsockname,rename,
socketpair,waitpid,bind,getpeername,listen,setsid,wait4}.S: Moved
to new directory sysdeps/unix/sysv/sysv4/linux.
* sysdeps/unix/sysv/linux: Directory removed.
* sysdeps/unix/sysv/i386/linux/{socket.S,sysdep.h,sysdep.S}: Moved
to new directory sysdeps/unix/sysv/sysv4/linux/i386.
* sysdeps/unix/sysv/linux/i386: Directory removed.
