* libio/ftello.c (ftello): Use _IO_off64_t for type of POS.
Check for the result overflowing off_t and fail with EOVERFLOW. * libio/ioftell.c (_IO_ftell): Likewise. * libio/iofgetpos.c (_IO_new_fgetpos): Likewise. * login/logwtmp.c (logwtmp): If sizeof ut_tv != sizeof struct timeval, use a temporary timeval on the stack for gettimeofday and copy it. * login/logout.c (logout): Likewise. Reported by Steven Munroe <sjmunroe@us.ibm.com>. * sysdeps/unix/sysv/linux/bits/statfs.h (struct statfs): Use __SWORD_TYPE instead of int for member types. (struct statfs64): Likewise. * sysdeps/unix/sysv/linux/alpha/bits/statfs.h: New file. * sysdeps/unix/sysv/linux/s390/bits/statfs.h: New file. * sysdeps/unix/sysv/linux/ia64/bits/statfs.h: File removed. * sysdeps/unix/sysv/linux/sparc/bits/statfs.h: File removed. * sysdeps/unix/sysv/linux/x86_64/bits/statfs.h: File removed. * sysdeps/unix/sysv/linux/sparc/bits/statvfs.h: Moved to ... * sysdeps/unix/sysv/linux/bits/statvfs.h: ... here. (ST_NODIRATIME): Restore fixed value of 2048. * sysdeps/unix/sysv/linux/alpha/bits/statvfs.h: File removed. * sysdeps/unix/sysv/linux/ia64/bits/statvfs.h: File removed. Rearranged <bits/types.h> definitions to reduce duplication. * sysdeps/generic/bits/types.h: Rewritten, using macros from <bits/wordsize.h> and new header <bits/typesizes.h>. * posix/Makefile (headers): Add bits/typesizes.h here. * sysdeps/generic/bits/typesizes.h: New file. * sysdeps/unix/sysv/linux/alpha/bits/typesizes.h: New file. * sysdeps/unix/sysv/linux/sparc/bits/typesizes.h: New file. * sysdeps/mach/hurd/bits/typesizes.h: New file. * sysdeps/unix/sysv/linux/alpha/bits/types.h: File removed. * sysdeps/unix/sysv/linux/bits/types.h: File removed. * sysdeps/unix/sysv/linux/ia64/bits/types.h: File removed. * sysdeps/unix/sysv/linux/mips/bits/types.h: File removed. * sysdeps/unix/sysv/linux/s390/bits/types.h: File removed. * sysdeps/unix/sysv/linux/sparc/bits/types.h: File removed. * sysdeps/unix/sysv/linux/x86_64/bits/types.h: File removed. * posix/sys/types.h [__USE_POSIX199506 || __USE_UNIX98]: Include <bits/pthreadtypes.h> here, not in <bits/types.h>. * signal/signal.h: Likewise. * streams/stropts.h: Include <bits/xtitypes.h>. * streams/Makefile (headers): Add bits/xtitypes.h here. * sysdeps/generic/bits/xtitypes.h: New file. * sysdeps/s390/bits/xtitypes.h: New file. * sysdeps/ia64/bits/xtitypes.h: New file. * sysdeps/x86_64/bits/xtitypes.h: New file. * sysvipc/Makefile (headers): Add bits/ipctypes.h here. * sysdeps/generic/bits/ipctypes.h: New file. * sysdeps/mips/bits/ipctypes.h: New file. * sysdeps/gnu/bits/shm.h: Include <bits/ipctypes.h>. * sysdeps/gnu/bits/msq.h: Likewise. * sysvipc/sys/ipc.h: Likewise. 2002-10-22 Roland McGrath <roland@redhat.com> * sysdeps/generic/libc-tls.c (_dl_tls_static_used): New variable. * sysdeps/generic/ldsodefs.h (struct rtld_global): New member `_dl_tls_static_used'. (TLS_STATIC_MIN): New macro. * elf/dl-reloc.c [USE_TLS] (allocate_static_tls): New function. (CHECK_STATIC_TLS): Use it.
