update from main arhive 970119cvs/libc-970120
Mon Jan 20 03:02:50 1997 Ulrich Drepper <drepper@cygnus.com> * Make-dist: Update and reformat copyright. * Makeconfig: Likewise. * assert/Makefile: Likewise. * bare/Makefile: Likewise. * ctype/Makefile: Likewise. * dirent/Makefile: Likewise. * gmon/Makefile: Likewise. * gnulib/Makefile: Likewise. * grp/Makefile: Likewise. * hurd/Makefile: Likewise. * intl/Makefile: Likewise. * mach/Makefile: Likewise. * malloc/Makefile: Likewise. * manual/Makefile: Likewise. * math/Makefile: Likewise. * po/Makefile: Likewise. * pwd/Makefile: Likewise. * resource/Makefile: Likewise. * setjmp/Makefile: Likewise. * socket/Makefile: Likewise. * string/Makefile: Likewise. * sunrpc/Makefile: Likewise. * sysdeps/alpha/Makefile: Likewise. * sysdeps/gnu/Makefile: Likewise. * sysdeps/m68k/fpu/switch/Makefile: Likewise. * sysdeps/m68k/fpu/switch/68881-sw.h: Likewise. * sysdeps/m68k/fpu/switch/switch.c: Likewise. * sysdeps/mach/Makefile: Likewise. * sysdeps/hurd/Makefile: Likewise. * sysdeps/sparc/Makefile: Likewise. * sysdeps/standalone/i960/nindy960/Makefile: Likewise. * sysdeps/standalone/m68k/m68020/mvme136/Makefile: Likewise. * sysdeps/unix/common/Makefile: Likewise. * sysdeps/unix/sysv/Makefile: Likewise. * sysdeps/unix/sysv/irix4/Makefile: Likewise. * sysdeps/unix/sysv/sco3.2/Makefile: Likewise. * sysdeps/unix/sysv/sysv4/Makefile: Likewise. * sysdeps/vax/Makefile: Likewise. * sysvipc/Makefile: Likewise. * wcsmbs/Makefile: Likewise. * wctype/Makefile: Likewise. * elf/rtld.c (dl_main): Objects in LD_PRELOAD environment variable are separated according to Sun docs by white space not colon. * locale/C-time.c (_nl_C_LC_TIME): Use empty string to initialize fields which are not defined for the C locale. * sysdeps/m68k/fpu/switch/Makefile: Don't use ansidecl.h in constructed files. * sysdeps/m68k/fpu/switch/68881-sw.h: Likewise. * sysdeps/m68k/fpu/switch/switch.c: Likewise. Sun Jan 19 19:43:31 1997 Andreas Jaeger <aj@arthur.pfalz.de> * time/strptime.c: Provide prototype for strptime_internal. Sun Jan 19 23:46:27 1997 Ulrich Drepper <drepper@cygnus.com> * glibcbug.in: We don't guarantee confidential handling. Set field to always contain `no'. Sun Jan 19 21:28:01 1997 Philippe De Muyter <phdm@info.ucl.ac.be> * intl/explodename.c: Include sys/types.h. * intl/l10nflist.c: Likewise. Sat Jan 18 22:15:26 1997 Richard Henderson <rth@tamu.edu> * config.make.in (install_root): New variable to make it easy to install glibc somewhere other than /. * shlib-versions: alpha-*-linux-* libc=6.1. Since sigset_t no longer fits in a register, we can't pass in the thread's initial mask so easily. Take this opportunity to simplify the clone implementation by only accepting a single void* argument. * sysdeps/unix/sysv/linux/alpha/clone.S: Only take one argument. * sysdeps/unix/sysv/linux/i386/clone.S: Likewise. * sysdeps/unix/sysv/linux/m68k/clone.S: Likewise. * sysdeps/unix/sysv/linux/sparc/clone.S: Likewise. * sysdeps/unix/sysv/linux/schedbits.h: Update clone prototypes. * sysdeps/unix/sysv/linux/alpha/ioctl-types.h: Remove. Default Linux version should be sufficient. * sysdeps/unix/sysv/linux/alpha/sigprocmask.c: The osf_sigprocmask system call wants the sigset dereferenced. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Add entries for __syscall_ustat and __syscall_xmknod. * sysdeps/unix/sysv/linux/alpha/xmknod.c: Include sys/sysmacros.h. * sysdeps/unix/sysv/linux/sigset.h: Use longs instead of ints. * sysdeps/unix/sysv/linux/tcsetattr.c: Fix pointer dereferences. * sysdeps/unix/sysv/linux/alpha/sigsuspend.c: Add comment about dependency to kernel type. * sysdeps/unix/sysv/linux/alpha/termbits.h: Correct comment.
