Wrong first day of week for "C" locale

There is http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=327025 about a similar behaviour some years ago, but it has been closed for quite a long time.

This may be a regression on libc6, or a locale issue, not sure. Assigning to GLIBC, marking as confirmed.

to test:

hggdh@xango2:~/libpst $ env LC_ALL=C cal
    January 2009
Sa Su Mo Tu We Th Fr
                1 2
 3 4 5 6 7 8 9
10 11 12 13 14 15 16
17 18 19 20 21 22 23
24 25 26 27 28 29 30
31
hggdh@xango2:~/libpst $ env LC_ALL=en_US.UTF8 cal
    January 2009
Su Mo Tu We Th Fr Sa
             1 2 3
 4 5 6 7 8 9 10
11 12 13 14 15 16 17

I can confirm that the output of this command has changed from Intrepid to Jaunty:

Intrepid:

    $ env LC_ALL=C cal
        January 2009
    Su Mo Tu We Th Fr Sa
                 1 2 3
     4 5 6 7 8 9 10
    11 12 13 14 15 16 17
    18 19 20 21 22 23 24
    25 26 27 28 29 30 31

Jaunty:

    $ env LC_ALL=C cal
        January 2009
    Sa Su Mo Tu We Th Fr
                    1 2
     3 4 5 6 7 8 9
    10 11 12 13 14 15 16
    17 18 19 20 21 22 23
    24 25 26 27 28 29 30
    31

This bug was fixed in the package glibc - 2.9-0ubuntu8

---------------
glibc (2.9-0ubuntu8) jaunty; urgency=low

  * Merge with Debian, glibc-2.9 branch, r3241.
  * Apply localedata patches. LP: #318507.
  * Remove progressions from expected test results.
