Wed May 22 22:10:01 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* stdlib/canonicalize.c: New file. * stdlib/stdlib.h: Declare canonicalize_file_name, realpath. * stdlib/Makefile (routines): Add canonicalize. * posix/unistd.h: Declare __canonicalize_directory_name_internal. Thu May 23 00:01:10 1996 Ulrich Drepper <drepper@cygnus.com> * db/recno/rec_seq.c: Prevent `sccsid' definition by using the same #if condition as in the other db files. * intl/Makefile: Add -Wno-unused CFLAGS for compilation of bindtextdom.c, finddomain.c, and localealias.c. * intl/dcgettext.c: Don't define prototype for getcwd() when compiling in glibc. * libio/cleanup.c: Add prototype for _IO_register_cleanup. * libio/filedoalloc.c, libio/fileops.c, libio/iopopen.c: Don't define _POSIX_SOURCE unconditionally. * libio/filedoalloc.c, libio/iopopen.c: Include <unistd.h> if compiling in glibc. * libio/fileops.c (_IO_file_close_it): Don't sync file, call flush instead. This relaxes the rules from POSIX.1 about changing the active handle a bit. * libio/iofopncook.c (struct _IO_cookie_file): Move definition into <libio.h>. Add prototypes for local functions to prevent warnings. * libio/iopopen.c: Change prototypes for _IO_fork, _IO_pipe, and _IO_DUP2 to contain complete parameter list. * libio/libio.h: Add definition of struct _IO_cookie_file. * libio/libioP.h: Add prototypes for _IO_vasprintf, _IO_vdprintf, and _IO_vsnprintf. * libio/memstream.c: Include <stdio.h>. * libio/stdio.h: Add prototypes for fopencookie, __stdio_gen_tempname, __vfscanf, __vsscanf, and __vsnprintf. * libio/strops.c: Avoid useless expression in `for' initializer. * locale/findlocale.c: Add some casts to prevent warnings. * locale/programs/locfile.c (write_locale_data): Don't use double `/' in locale binary file. * posix/unistd.h: Remove prototype for `reboot'. Update from bind-4.9.4-T1A. * resolv/Makefile (routines): Add inet_ntop and inet_pton. * resolv/arpa/nameser.h: Add definition of IN6ADDRSZ. * resolv/gethnamaddr.c, resolv/getnetnamadr.c, resolv/res_comp.c, resolv/res_debug.c, resolv/res_init.c * resolv/inet_ntop.c, resolv/inet_pton.c: New files. * resolv/resolv.h: Add RES_USE_INET6 flag. (__dn_isvalid): Renamed to __res_dnok. Add prototypes for __res_ownok and __res_mailok. * stdio-common/Makefile: Add -Wno-unused to CFLAGS for _itoa.c. * stdio-common/getline.c, stdio-common/vfscanf.c, sysdeps/posix/tempname.c: Don't use <ansidecl.h> anymore. * sysdeps/unix/sysv/linux/Makefile [$subdir == misc] (sysdep_routines): Add s_reboot. (install-others): Add $(includedir)/sys/syscall.h. New rule for $(includedir)/sys/syscall.h to produce from <asm/unistd.h>. * sysdeps/unix/sysv/linux/reboot.c: New file. Make single argument function call 3 argument system call. * sysdeps/unix/sysv/linux/sys/reboot.h: New file. Linux specific definition for reboot function. * sysdeps/unix/sysv/linux/syscall.h: Remove old and obsolete comment. * sysdeps/unix/sysv/linux/syscalls.list: Rename function for reboot syscall to __syscall_reboot. * wcsmbs/wchar.h: Protect prototypes for wcstof and wcstold by __USE_GNU, not USE_GNU. Tue May 21 21:55:49 1996 David Mosberger-Tang <davidm@AZStarNet.com> * locale/programs/charset.c, locale/programs/ld-collate.c: Add casts to prevent warnings on 64-bit machines. * locale/programs/ld-monetary.c: Don't do unnecessary tests for int_frac_digits and frac_digits which only produce warnings. Mon May 13 23:45:29 1996 David Mosberger-Tang <davidm@AZStarNet.com> * inet/arpa/inet.h: Backup return type of inet_addr to u_long. * resolv/inet_addr.c: Likewise. * resolv/Makefile (distribute): Add res_hconf.h (routines): Add res_hconf. * resolv/gethnamaddr.c: Add support for /etc/host.conf. * resolv/res_init.c: Initialize /etc/host.conf reader. * resolv/res_hconf.c, resolv/res_hconf.h: New files. Implementation of reading /etc/host.conf. Wed May 22 21:21:15 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * Rules (%.out rules): Prepend $($*-ENV) to the command. * sysdeps/unix/sysv/linux/i386/brk.c (___brk_addr): Define as weak alias for __curbrk. Wed May 22 19:37:27 1996 Miles Bader <miles@gnu.ai.mit.edu> * hurd/hurdexec.c (_hurd_exec): Pass INIT_TRACEMASK. * hurd/hurdmsg.c (set_int): Support INIT_TRACEMASK. Wed May 22 18:47:31 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * sysdeps/mach/hurd/getcwd.c (_hurd_canonicalize_directory_name_internal): New function, broken out of __getcwd. (__getcwd): Use it. (__canonicalize_directory_name_internal): New function using it. * sysdeps/posix/getcwd.c (__canonicalize_directory_name_internal): New function, broken out of __getcwd. (__getcwd): Use it. Wed May 22 18:14:05 1996 Miles Bader <miles@gnu.ai.mit.edu> * string/argz-create.c (__argz_create): Correctly calculate length. * string/argz-extract.c (__argz_extract): Add terminating 0 entry. * hurd/hurdstartup.c (_hurd_startup): ... and don't so here. [HAVE_VMSDIR_H]: Include "vmsdir.h". (glob) [VMS]: Don't grok ~.
