[BZ #473, BZ #487]
2004-10-27 Derek R. Price <derek@ximbiot.com> [BZ #487] This change is imported from gnulib. * time/mktime.c (not_equal_tm) [DEBUG]: Remove redundant check. 2004-10-24 Paul Eggert <eggert@cs.ucla.edu> [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.
