* 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.
