Update
1999-07-01 Cristian Gafton <gafton@redhat.com>
* time/strptime.c (strptime): Initialize the tm struct first to avoid
returning bogus results on incomplete data.
(strptime_internal): day_of_the_week() requres bith tm_mon and
tm_mday to be initializaed.
Computer them first if they are not given.
(strptime_internal): (have_mon, have_mday): New variables.
