[BZ #487] This change is imported from gnulib.
* time/mktime.c (not_equal_tm) [DEBUG]: Remove redundant check.

[BZ #473]
* time/tst-mktime.c (main): Don't assume that mktime fails
when given time stamps before 1970. It returns negative
time_t values instead, for compatibility with BSD.
* time/tst-mktime2.c: New file.
* time/Makefile (tests): Add it.
[BZ #473] Import from gnulib. Revamp to avoid several problems near
time_t extrema, and on hosts with 64-bit time_t and 32-bit int.
This fixes Debian bug 177940.
* time/mktime.c (TIME_T_MIDPOINT): New macro.
(ydhms_diff): Renamed from ydhms_tm_diff, with a new signature,
which avoids overflow problems on hosts with 64-bit time_t and
32-bit int. All callers changed. Now an inline function.
Verify at compile-time that long int is wide enough to avoid
these overflow problems.
(guess_time_tm): New function.
(__mktime_internal): Use it. Avoid overflow when computing yday on
hosts with 64-bit long and 32-bit int. Remove tests for 69;
no longer needed. Use if rather than #ifdef for LEAP_SECONDS_POSSIBLE
so that the code is checked by more compilers.
Do not rely on floating point to probe: stick to integer arithmetic,
to avoid potential porting problems.
Repair potential overflow correctly in the Southern Hemisphere.
(localtime_offset): Add a FIXME for the case where time_t is unsigned.
This directory contains the version 2.3.3 release of the GNU C Library.
Many bugs have been fixed since the last release.
Some bugs surely remain.
As of this release, the GNU C library is known to run on the following
configurations:
*-*-gnu GNU Hurd
i[3456]86-*-linux-gnu Linux-2.x on Intel
m68k-*-linux-gnu Linux-2.x on Motorola 680x0
alpha*-*-linux-gnu Linux-2.x on DEC Alpha
powerpc-*-linux-gnu Linux and MkLinux on PowerPC systems
powerpc64-*-linux-gnu Linux-2.4.19+ on 64-bit PowerPC systems
sparc-*-linux-gnu Linux-2.x on SPARC
sparc64-*-linux-gnu Linux-2.x on UltraSPARC 64-bit
arm-*-none ARM standalone systems
arm-*-linux Linux-2.x on ARM
arm-*-linuxaout Linux-2.x on ARM using a.out binaries
mips*-*-linux-gnu Linux-2.x on MIPS
ia64-*-linux-gnu Linux-2.x on ia64
s390-*-linux-gnu Linux-2.x on IBM S/390
s390x-*-linux-gnu Linux-2.4+ on IBM S/390 64-bit
sh-*-linux-gnu Linux-2.x on Super Hitachi
cris-*-linux-gnu Linux-2.4+ on CRIS
x86-64-*-linux-gnu Linux-2.4+ on x86-64
Former releases of this library (version 1.09.1 and perhaps earlier
versions) used to run on the following configurations:
alpha-dec-osf1
i[3456]86-*-bsd4.3
i[3456]86-*-isc2.2
i[3456]86-*-isc3
i[3456]86-*-sco3.2
i[3456]86-*-sco3.2v4
i[3456]86-*-sysv
i[3456]86-*-sysv4
i[3456]86-force_cpu386-none
i[3456]86-sequent-bsd
i960-nindy960-none
m68k-hp-bsd4.3
m68k-mvme135-none
m68k-mvme136-none
m68k-sony-newsos3
m68k-sony-newsos4
m68k-sun-sunos4
mips-dec-ultrix4
mips-sgi-irix4
sparc-sun-solaris2
sparc-sun-sunos4
Since no one has volunteered to test and fix the above configurations,
these are not supported at the moment. It's expected that these don't
work anymore. Porting the library is not hard. If you are interested
in doing a port, please contact the glibc maintainers by sending
electronic mail to <bug-glibc@gnu.org>.
There are some add-ons which can be used together with GNU libc. They
are designed in a way to ease the installation by integrating them in
the libc source tree. Simply get the add-ons you need and use the
--enable-add-ons option of the `configure' script to tell where the
add-ons are found. Please read the FAQ file for more details.
See the file INSTALL to find out how to configure, build, install, and port
the GNU C library. You might also consider reading the WWW pages for the
GNU libc at http://www.gnu.org/software/libc/libc.html.
The GNU C Library is completely documented by the Texinfo manual found
in the `manual/' subdirectory. The manual is still being updated and
contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like.
Please send comments on the manual to <bug-glibc-manual@gnu.org>, and
not to the library bug-reporting address.
The file NOTES contains a description of the feature-test macros used
in the GNU C library, explaining how you can tell the library what
facilities you want it to make available.
We prefer to get bug reports sent using the `glibcbug' shell script which
is installed together with the rest of the GNU libc to <bugs@gnu.org>.
Simply run this shell script and fill in the information. Nevertheless
you can still send bug reports to <bug-glibc@gnu.org> as normal electronic
mails.
The GNU C Library is free software. See the file COPYING.LIB for copying
conditions, and LICENSES for notices about a few contributions that require
these additional notices to be distributed.
