Reported by Andreas Jaeger <aj@arthur.rhein-neckar.de>. 1997-11-12 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/wordsize-32/inttypes.h (SIG_ATOMIC_MAX): Correct value. * sysdeps/wordsize-64/inttypes.h (SIG_ATOMIC_MAX): Likewise. 1997-11-11 Paul Eggert <eggert@twinsun.com> Add overflow checking for 64-bit time_t and 32-bit int. * time/time.h (__offtime): Now returns int. * time/offtime.c (__offtime): Return nonzero if successful; check for tm_year overflow. (DIV): New macro. (LEAPS_THRU_END_OF): Handle negative years correctly. * time/tzset.c (__tz_convert): Return NULL if offtime cannot convert. * time/mktime.c (ranged_convert): New function. (ydhms_tm_diff): Return nonzero if TP is null. (__mktime_internal): Handle cases correctly even if they are near or past the limits of time_t values that can be broken down to struct tm. (print_tm, check_result, main): Diagnose localtime failures. * manual/time.texi: Document the fact that localtime returns 0 if the time can't be represented. 1997-11-12 06:03 Ulrich Drepper <drepper@cygnus.com> * time/strftime.c (memset_space, memset_zero): Use MEMPCPY, not mempcpy. Patch by Ken'ichi Handa <handa@etl.go.jp>. * manual/time.texi: Document %F and %f format for strftime. * manual/arith.texi: Document copysign, nextafter and nan. 1997-11-06 Andreas Jaeger <aj@arthur.rhein-neckar.de> * test-installation.pl: New file.
