Wed Sep 18 00:25:41 1996 Ulrich Drepper <drepper@cygnus.com> * time/strftime.c (strftime): The T_FMT_AMPM string may be empty. Tue Sep 17 20:27:18 1996 Ulrich Drepper <drepper@cygnus.com> * math/Makefile (extra-libs-others): Use $(extra-libs) instead of $(extra-libc).

Sun Sep 15 12:46:44 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * configure.in: If $os contains a hyphen add the part before the hyphen to $ostry. Sun Sep 15 18:14:02 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/m68k/fpu/__math.h (__ieee754_pow, __ieee754_powf, __ieee754_powl): Rename local variable i to __i. (__ieee754_atan2, __ieee754_atan2f, __ieee754_atan2l): New inline functions. * sysdeps/m68k/fpu/e_atan2.c, sysdeps/m68k/fpu/e_atan2f.c, sysdeps/m68k/fpu/e_atan2l.c: New files. 1996-09-15 Paul Eggert <eggert@twinsun.com> * manual/time.texi: Change `range X to Y' to `range X through Y', to avoid ambiguity in English. (strftime): Numbers that do not have a range indicated are not padded. Describe E and O modifiers. %g, %G, %u: New formats. %C, %y, %Y: Describe behavior on negative years. %e: Fix typo (was labeled %d). %l, %V: Fix typo in range. %M, %S, %U, %w, %W: Give ranges. %p: Clarify how noon and midnight are handled for AM and PM. %s: Clarify leap second handling. %r: Now locale-defined. %C, %D, %e, %h, %n, %r, %t, %T: Say that they are POSIX.2 extensions. %z: Say that it is a GNU extension. %Z: Wording fix. * time/strftime.c: (strftime): %V: Fix mishandling of week numbers near year boundaries. %g, %G: New formats (suggested by Arthur David Olson). %U, %W: Use inline expression instead of `week' function. %C, %y: Handle negative years portably. %C, %Y: Use width 1, since values can be arbitrarily wide. %r: Use T_FMT_AMPM format if _NL_CURRENT is defined. %u: New Posix.2 format. %w: Width is 1, not 2. (iso_week_days): New function, for %V, %G, %g. (week): Remove; it didn't handle %V correctly. (__isleap): New macro. (mbsinit): Use arg, to pacify GCC -Wall. 1996-09-13 Paul Eggert <eggert@twinsun.com> * time/strftime.c (strftime): If using the GNU C library, do not bother to check for multibyte encodings, since they're safe in formats. Otherwise: - Check for multibyte encodings when encountering any character that is not in the basic execution character set of the C Standard. - Use mbrlen (if available) instead of mblen, to avoid modifying mblen's internal state. - Do not assume that '%' cannot appear as the first character of a multibyte character sequence, since this is possible when not in the initial shift state. (HAVE_MBRLEN, MULTIBYTE_IS_FORMAT_SAFE): Define if _LIBC is defined. (DO_MULTIBYTE): New macro. (<ctype.h>): Do not include. (<wchar.h>): Include if HAVE_MBRLEN. (mbstate_t, mbrlen, mbsinit): Define if ! HAVE_MBRLEN. (mbstate_zero): New constant. 1996-09-12 Paul Eggert <eggert@twinsun.com> * time/strftime.c (strftime): Use an empty zone if it can't be determined; POSIX.2 requires this. Use plain `int' for pad and modifier (which now contain char value). Use plain `int' for number_value, to print negative values correctly. Use plain `int' for digits; there was no need to make it unsigned. Initialize subfmt consistently. Remove incorrect code for %EC and %Ey; they aren't implemented yet. For %O, if there is no alternate digit, output Ascii instead of "". Output the `%' of an unknown format; this is most likely the right thing to do if a multibyte string has been misparsed. Thu Sep 12 23:23:13 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * stdio-common/scanf7.c (main): Remove extra conversion from printf format string. Thu Sep 12 23:01:16 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * stdlib/test-canon.c (tests): Rename structure member from errno to error, all uses changed. Thu Sep 12 20:08:06 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/m68k/fpu/__math.h (__ldexp, __ldexpf, __ldexpl): Removed. * sysdeps/m68k/fpu/s_ldexp.c, sysdeps/m68k/fpu/s_ldexpf.c, sysdeps/m68k/fpu/s_ldexpl.c: Removed, use generic implementation instead. * sysdeps/m68k/fpu/s_scalbn.c, sysdeps/m68k/fpu/s_scalbnf.c, sysdeps/m68k/fpu/s_scalbnl.c: Replaced with old contents of s_ldexp.c, s_ldexpf.c and s_ldexpl.c, resp., suitably adpted. * sysdeps/m68k/fpu/__math.h (__frexp, __frexpf, __frexpl): Return value must be in [0.5, 1), not [1, 2). Reported by Chris Lawrence. (__ilogb, __ilogbf, __ilogbl): Check for argument being zero. (__scalbn, __scalbnf, __scalbnl): Use second argument directly.

Thu Sep 12 19:59:24 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/libm-ieee754/e_acoshl.c: Fix typos. * sysdeps/libm-ieee754/s_cbrtl.c: Remove unused variable. Thu Sep 12 19:56:07 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * inet/herrno.c (__h_errno_location): Fix return type. Tue Sep 17 10:51:58 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * malloc/memalign.c (memalign): Only acquire __libc_malloc_lock for actual modifications to global state. Fri Sep 13 01:21:36 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * sysdeps/mach/Makefile (includes): Add -I$(common-objpfx)mach/. * sysdeps/mach/hurd/Makefile (includes): Add -I$(common-objpfx)hurd/. Reported by Marcus Daniels. * sysdeps/generic/schedbits.h (struct sched_param): Renamed from struct sched_params. * sysdeps/stub/sched_setp.c (__sched_setparam): struct sched_params -> struct sched_param. * sysdeps/stub/sched_getp.c (__sched_getparam): Likewise. * sysdeps/stub/sched_sets.c (__sched_setscheduler): Likewise. Thu Sep 12 23:58:25 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * sysdeps/mach/libc-lock.h (__libc_cleanup_region_start): Fix syntax error. * stdio-common/Makefile: Put lockfile in routines unconditionally. Define _MT_SAFE_IO if using for libio and compiling reentrant libc. * stdio-common/vfprintf.c (__flockfile, __funlockfile): Declare this always, not just if _LIBC_REENTRANT. (__funlockfile): Don't use weak_extern for this one; __libc_cleanup_region_end might be defined and the use of __funlockfile can't be protected the way the use of __flockfile can be. * sched.h: New file. Helper to access posix/sched.h. Thu Sep 12 12:33:52 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * sysdeps/mach/hurd/dl-cache.c: Delete second copy of file accidentally added on. * sysdeps/stub/intr-msg.h: New file. * stdio-common/vfprintf.c: Include <libc-lock.h>. * stdio-common/vfscanf.c: Include <libc-lock.h>. * sysdeps/mach/libc-lock.h (__libc_cleanup_region_start): New macro.

/* These are defined by the user (or the compiler)

|
|
|
__STRICT_ANSI__ ANSI Standard C.
|
|
_POSIX_SOURCE IEEE Std 1003.1.
|
|
_POSIX_C_SOURCE If ==1, like _POSIX_SOURCE; if ==2 add IEEE Std 1003.2.
|
|
_BSD_SOURCE ANSI, POSIX, and 4.3BSD things.
|
|
_SVID_SOURCE ANSI, POSIX, and SVID things.
|
|
_GNU_SOURCE All of the above, plus GNU extensions.
|
|
_REENTRANT Select additionally reentrant object.
|
|
_THREAD_SAFE Same as _REENTRANT, often used by other systems.
|
|
|
|
The `-ansi' switch to the GNU C compiler defines __STRICT_ANSI__.
|
|
If none of these are defined, the default is all but _GNU_SOURCE.
|
|
If more than one of these are defined, they accumulate.
|
|
For example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE
|
|
together give you ANSI C, 1003.1, and 1003.2, but nothing else.
|

These are defined by this file and are used by the

header files to decide what to declare or define:

__USE_POSIX Define IEEE Std 1003.1 things.
|
|
__USE_POSIX2 Define IEEE Std 1003.2 things.
|
|
__USE_BSD Define 4.3BSD things.
|
|
__USE_SVID Define SVID things.
|

__USE_MISC Define things common to BSD and System V Unix.
|
|
__USE_GNU Define GNU extensions.
|

__USE_REENTRANT Define reentrant/thread-safe *_r functions.

__FAVOR_BSD Favor 4.3BSD things in cases of conflict.

explicitly undefined if they are not explicitly defined.
