mktime: improve heuristic for ca-1986 Indiana DST
Problem reported by Mark Krenz <https://bugs.gnu.org/48085>.
* lib/mktime.c (__mktime_internal): Be more generous about
accepting arguments with the wrong value of tm_isdst, by falling
back to a one-hour DST difference if we find no nearby DST that is
unusual. This fixes a problem where "1986-04-28 00:00 EDT" was
rejected when TZ="America/Indianapolis" because the nearest DST
timestamp occurred in 1970, a temporal distance too great for the
old heuristic. This also also narrows the search a bit, which
is a minor performance win.
* m4/mktime.m4 (gl_FUNC_MKTIME_WORKS):
Check for putenv failures and for Bug#48085.
* tests/test-parse-datetime.c (main):
Test for setenv failures and for Bug#48085.
