Update.
1998-11-27 Philip Blundell <pb@nexus.co.uk> Fixes to allow compilation with static NSS: * nss/Makefile: Make explicit the dependency of getent on libnss_files.a. [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. (struct kernel_sigaction): Rename sa_handler to k_sa_handler. * sysdeps/unix/sysv/linux/mips/bits/time.h: Removed, we can use the general linux version. * sysdeps/unix/sysv/linux/mips/bits/stat.h (_STAT_VER_KERNEL): Added. * sysdeps/unix/sysv/linux/mips/bits/socket.h: Update file. 1998-09-03 Philip Blundell <pb@nexus.co.uk> * sysdeps/arm/bits/endian.h (__FLOAT_WORD_ORDER): Define to big endian. * math/math_private.h: Use __FLOAT_WORD_ORDER rather than BYTE_ORDER. * string/endian.h: If __FLOAT_WORD_ORDER wasn't defined by <bits/endian.h>, make it the same as __BYTE_ORDER. 1998-11-26 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * Makeconfig ($(common-objpfx)sysd-dirs): Use automatic variables if possible. ($(common-objpfx)sysd-sorted): Likewise. 1998-11-27 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/libm-ieee754/e_log.c (__ieee754_log): Add declaration of local variables t1,t2 only if needed. * sysdeps/libm-ieee754/s_truncf.c (__truncf): Likewise. * sysdeps/libm-ieee754/s_trunc.c (__trunc): Likewise. * sysdeps/mips/mul_1.S (Loop): Add closing comment to avoid warning. 1998-11-27 Andreas Jaeger <aj@arthur.rhein-neckar.de> * math/math.h: Add brace to correct #if expression. 1998-11-26 Philip Blundell <philb@gnu.org> Undo change of 1998-11-12: * sysdeps/unix/sysv/linux/netlink/netlink.h: Deleted. * sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Remove netlink/netlink.h. * sysdeps/unix/sysv/linux/Dist: Likewise. 1998-11-22 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/nis_print.c (nis_print_entry): Changes to match Solaris output. 1998-11-26 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/generic/pselect.c (__pselect): Change interface, set/restore sigmask. * misc/sys/select.h: Change declaration according to Stevens' Unix Network Programming. * include/sys/select.h (__pselect): Likewise.
