From 036cc82fbc47a632c1ed3a310a1a29365fe48d3d Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 26 Jul 1996 04:35:31 +0000 Subject: Fri Jul 26 04:41:28 1996 Ulrich Drepper * intl/libintl.h: Define optimizing macros if __OPTIMIZE__ is defined, not __OPTIMIZED. (_nl_msg_cat_cntr): Move declaration outside macro definition to prevent "nested extern" warning. (dcgettext): Rename local variable `result' to `__result'. Thu Jul 25 22:46:30 1996 Roland McGrath * locale/programs/localedef.c (__progname): Remove decl. (main): Use program_invocation_short_name instead of __progname. (usage): Use program_invocation_name instead of __progname. Fri Jul 26 03:46:08 1996 Ulrich Drepper * catgets/gencat.c: Use "libc" instead of PACKAGE. * locale/localedef.c: Ditto. * locale/locale.c: Ditto. * locale/findlocale.c (_nl_find_locale): Little optimization. Use new function `strndup'. * locale/loadlocale.c: Little optimization. Use constant value from `_nl_category_num_items' instead of byte-order dependend value from file. * locale/programs/ld-time.c (time_add): Correct string constant. * locale/programs/locale-spec.c: New file. * locale/programs/locale.c: Call `locale_special' function if no other field matches. * locale/programs/localedef.c: No need to define `program_name'. Use global variable `__progname'. * locale/programs/locfile.c (write_locale_data): Always write LC_MESSAGES data in LC_MESSAGES/SYS_LC_MESSAGES file. This is necessary since message catalogs are also installed in the LC_MESSAGES/ directory. * locale/programs/stringtrans.c (ADDC): Correctly use `encode_char' function instead of writing single bytes. (encode_char): Also handle little endian. * locale/setlocale.c (new_composite_name): Little optimization. Use return value of `memcpy'. * misc/ttyent.h: Pretty print prototypes, add missing parameter names, prepend parameter names with __ and use `__const' instead of `const'. * posix/unistd.h: Ditto. * stdlib/stdlib.h: Ditto. * string/string.h: Ditto. * posix/getconf.c: De-ASNI-fy. Recognize POSIX.2 constant names. Use `error' function instead of doing it by hand. * sysdeps/posix/sysconf.c: De-ANSI-fy. Handle _SC_COLL_WEIGHTS_MAX. * sysdeps/stub/sysconf.c: Handle _SC_CHARCLASS_NAME_MAX, _SC_COLL_WEIGHTS_MAX, _SC_EQUIV_CLASS_MAX, _SC_2_LOCALEDEF since these do depend on the platform. Add POSIX.4 symbols. * posix/posix2_lim.h: Add missing definition of _POSIX2_COLL_WEIGHTS_MAX. Change _POSIX2_EQUIV_CLASS_MAX and _POSIX2_CHARCLASS_NAME_MAX to high values since we have no fixed limit. * sysdeps/generic/confname.h: Add _SC_PAGE_SIZE as alias for _SC_PAGESIZE for buggy systems (= HP UX) out there. * wcsmbs/Makefile (routines): Add mbsnrtowcs and wcsnrtombs. * wcsmbs/mbsnrtowcs.c: New file. Non-standard implementation. * wcsmbs/wcsnrtombs.c: Ditto. * wcsmbs/wchar.h [__USE_GNU]: Add prototypes for mbsnrtowcs and wcsnrtombs. Thu Jul 25 00:25:54 Richard Henderson * nss/nss_db/db-XXX.c: Kill trailing ; from lock defn as a matter of course. * nss/getXXent_r.c: Likewise. * nss/nsswitch.c: Likewise. * nss/nss_files/files-XXX.c: Likewise. * sysdeps/mach/hurd/dirstream.h (struct __dirstream): Likewise. * sysdeps/unix/bsd/telldir.c (struct record): Likewise. * sysdeps/unix/dirstream.h (struct __dirstream): Likewise. --- posix/getconf.c | 69 +++++++++++++++++++++++++++++------------------------- posix/posix2_lim.h | 18 ++++++++++---- posix/unistd.h | 21 +++++++++-------- 3 files changed, 62 insertions(+), 46 deletions(-) (limited to 'posix') diff --git a/posix/getconf.c b/posix/getconf.c index 699cf67bfe..6d78205a88 100644 --- a/posix/getconf.c +++ b/posix/getconf.c @@ -16,18 +16,19 @@ License along with the GNU C Library; see the file COPYING.LIB.
