[build_static_nss]: Define $(otherlibs) appropriately. * nss/Depend: Add a dependency on `resolv'. 1998-11-27 Andreas Jaeger <aj@arthur.rhein-neckar.de> Partial support for MIPS ISO C 9x exception handling: * sysdeps/mips/fclrexcpt.c: New file. * sysdeps/mips/ftestexcept.c: New file. * sysdeps/mips/fgetexcptflg.c: New file. * sysdeps/mips/fesetround.c: New file. * sysdeps/mips/fegetround.c: New file. * sysdeps/mips/fegetenv.c: New file. * sysdeps/mips/fesetenv.c: New file. * sysdeps/mips/feupdateenv.c: Likewise. * sysdeps/mips/bits/fenv.h: New file. 1998-11-28 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/unix/sysv/linux/mips/bits/signum.h: Remove inclusion of <asm/signal.h> and add needed symbols from <asm/signal.h>; bring in sync with linux specific version. Patches by Ralf Baechle <ralf@uni-koblenz.de> for mips-linux: * sysdeps/unix/mips/sysdep.S: Define _errno as weak_alias, rewrite errno declaration. * sysdeps/unix/sysv/linux/mips/ustat.c: Use INLINE_SYSCALL instead of calling __syscall_*. * sysdeps/unix/sysv/linux/mips/xmknod.c: Likewise. * sysdeps/unix/sysv/linux/mips/syscalls.list: Update entries. * sysdeps/unix/sysv/linux/mips/sys/syscall.h: Add missing SYS_* constants, correct values according to Linux 2.1.130. * sysdeps/unix/sysv/linux/mips/pwrite.c: New file. * sysdeps/unix/sysv/linux/mips/pwrite64.c: New file. * sysdeps/unix/sysv/linux/mips/pread.c: New file. * sysdeps/unix/sysv/linux/mips/pread64.c: New file. * sysdeps/mips/Makefile (sysdep_routines): Use += instead of a :=. * sysdeps/unix/sysv/linux/mips/bits/ipc.h: Remove ipc_kludge. * sysdeps/unix/sysv/linux/mips/xstatconv.c: New file. * sysdeps/unix/sysv/linux/mips/xstat.c: Removed. * sysdeps/unix/sysv/linux/mips/sys/ucontext.h: New file. * sysdeps/unix/sysv/linux/mips/kernel_termios.h: Add copyright message, change name of include protection, remove inclusion of <bits/termios.h>. * sysdeps/unix/sysv/linux/mips/kernel_sigaction.h (old_kernel_sigaction): Define.
