[BZ #1033]
* time/mktime.c: Import from gnulib.
The following macros are now consistent with other gnulib code.
This does not change mktime's behavior.

(time_t_is_integer): Use it.
(TYPE_TWOS_COMPLEMENT): New macro.
(twos_complement_arithmetic): Use it.
(TYPE_ONES_COMPLEMENT): New macro.
(TYPE_MINIMUM, TYPE_MAXIMUM): Now supports signed-magnitude.
mktime doesn't use this, but the code now matches other gnulib code.
(ranged_convert): Pacify GCC 4.0 in a different way, which
generates a few bytes less code.
(ranged_convert, __mktime_internal): When calling a function via a
pointer P, use P () rather than (*P) (), as we now assume C89 or
better.

[BZ #535]
* time/difftime.c: Fix a double-rounding bug on hosts with
64-bit time_t and long double being IEEE double. Also, port
to more valid C99 hosts, even those that have padding bits.
Don't include <values.h> since it is marked as an obsolescent
interface. Include <limits.h>, <float.h>, and <stdint.h> instead.
(TYPE_BITS, TYPE_FLOATING, TYPE_SIGNED): New macros.
(subtract): New static function, that works correctly without
double-rounding, even on hosts with 64-bit time_t. Also cater
to hosts with padding bits.
(__difftime): Use it. Use DBL_MANT_DIG and LDBL_MANT_DIG to
determine whether floating types are wide enough: the old
test (which used sizeof) could in theory report the wrong results
on hosts with padding bits in floating-point values.

[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.
* time/mktime.c (leapyear, ydms_tm_diff): Year is of type
long int, not int, to avoid problems when tm_year == INT_MAX
and tm_mon > 12.
(__mktime_intenral): Compute year using long int arithmetic,
not int arithmetic, to avoid problems on hosts where time_t
and long are 64 bits but int is 32.
* time/mktime.c [!_LIBC] (__mktime_internal): Define to
mktime_internal, to avoid clashes with any __mktime_internal
function defined in the standard library.
* time/mktime.c (__isleap): Remove; all uses replaced by:
(leapyear): New function, which avoids overflow by not adding
1900 to year before testing whether it is a leap year.
