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. + 2004-11-11 Simon Josefsson <jas@extundo.com> [BZ #542] |
