tst-strptime.c: More tests

[Andreas Jaeger]

glibc 2.1 or 2.1.1 (I'm not sure) fail AFAIK on the this test
according to a posting in a german newsgroup.  

#include <stdio.h>
#include <time.h>

int main()
{
    struct tm foo;
    strptime("17410105012000","%H%M%S%d%m%Y", &foo);
    puts(asctime(&foo));
    return 0;
}

(gdb) print foo
$1 = {tm_sec = 10, tm_min = 41, tm_hour = 17, tm_mday = 5, tm_mon = 11,
  tm_year = -1900, tm_wday = 134514064, tm_yday = 134513648,
  tm_isdst = 1074113551, __tm_gmtoff__ = 0, __tm_zone__ = 0xbffffd4c ""}

This is fixed in glibc 2.1.2! I've made a regression test out of this.

	struct tm.
