+ mktime: fix bug with Y2038 DST transition
+ [BZ#23789]
+ * time/mktime.c (ranged_convert): On 32-bit platforms, don’t
+ mishandle a DST transition that jumps over the Y2038 boundary.
+ No such DST transitions are known so this is only a theoretical
+ bug, but we might as well do things right.

mktime: make more room for overflow
[BZ#23789]
* time/mktime.c (long_int): Now 4⨯ int, not just 3⨯.
