Update.
1998-10-25 Ulrich Drepper <drepper@cygnus.com> * include/features.h: Define __USE_POSIS199506 is _POSIX_C_SOURCE is greater or equal than 199506L. * sysdeps/generic/bits/types.h (__fd_set): Define element as fds_bits only is __USE_XOPEN. Otherwise use __fds_bits. * sysdeps/unix/sysv/linux/alpha/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/bits/types.h: Likewise. * sysdeps/unix/sysv/sysv4/solaris2/bits/types.h: Likewise. 1998-10-24 H.J. Lu <hjl@gnu.org> * locale/programs/charmap.c (parse_charmap): Accept tok_string for <code_set_name>. 1998-10-25 H.J. Lu <hjl@gnu.org> * locale/programs/ld-ctype.c (ctype_finish): Also check <space>. 1998-10-25 Ulrich Drepper <drepper@cygnus.com> * signal/signal.h: Include bits/sigthread.h only if __USE_POSIX199506. * sysdeps/unix/sysv/linux/bits/types.h: Include pthreadtypes.h only if __USE_POSIX199506 or __USE_UNIX98. 1998-10-24 22:34 -0400 Zack Weinberg <zack@rabi.phys.columbia.edu> * string/bits/string2.h: Inline strdup+friends only if __USE_MISC || __USE_GNU (prevents namespace pollution). 1998-10-24 H.J. Lu <hjl@gnu.org> * sysdeps/unix/sysv/linux/alpha/bits/fcntl.h (LOCK_SH, LOCK_EX, LOCK_NB, LOCK_UN): Protect with __USE_BSD. * sysdeps/unix/sysv/linux/i386/bits/fcntl.h (LOCK_SH, LOCK_EX, LOCK_NB, LOCK_UN): Likewise. * sysdeps/unix/sysv/linux/mips/bits/fcntl.h (LOCK_SH, LOCK_EX, LOCK_NB, LOCK_UN): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/fcntl.h (LOCK_SH, LOCK_EX, LOCK_NB, LOCK_UN): Likewise. * sysdeps/unix/sysv/linux/bits/fcntl.h (LOCK_SH, LOCK_EX, LOCK_NB, LOCK_UN): Likewise. 1998-10-24 H.J. Lu <hjl@gnu.org> * libio/ioseekoff.c (_IO_seekoff): Check the valid dir value. * libio/rewind.c (rewind): Clear the error. 1998-10-24 H.J. Lu <hjl@gnu.org> * grp/grp.h (getgrent_r, getgrgid_r, getgrnam_r): Add "__" to "buffer". 1998-10-24 H.J.

Lu <hjl@gnu.org> * signal/signal.h (timespec, siginfo_t, sigwaitinfo, sigtimedwait, sigqueue): Protect with __USE_POSIX199309. 1998-10-24 H.J. Lu <hjl@gnu.org> * time/time.h (timespec): Protect with __USE_POSIX199309 instead of __USE_POSIX. 1998-10-24 H.J. Lu <hjl@gnu.org> * libio/fileops.c (_IO_new_file_seekoff): Always resync with the kernel file offset. * libio/oldfileops.c (_IO_old_file_seekoff): Likewise.
