Notices in file.inc

Hi there!

With current cvs I get the following notices:

   Notice: Constant UPLOAD_ERR_OK already defined in
   /home/killes/public_html/includes/file.inc on line 15 Notice:
Constant
   UPLOAD_ERR_INI_SIZE already defined in
   /home/killes/public_html/includes/file.inc on line 16 Notice:
Constant
   UPLOAD_ERR_FORM_SIZE already defined in
   /home/killes/public_html/includes/file.inc on line 17 Notice:
Constant
   UPLOAD_ERR_PARTIAL already defined in
   /home/killes/public_html/includes/file.inc on line 18 Notice:
Constant
   UPLOAD_ERR_NO_FILE already defined in
   /home/killes/public_html/includes/file.inc on line 19

Those constants are defined in file.inc, but nowhere else in Drupal.

Cheers,
