Since everybody seems to be confused, here is paragraph 3 of LGPL 2.1:

    3. You may opt to apply the terms of the ordinary GNU General Public
  License instead of this License to a given copy of the Library.  To do
  this, you must alter all the notices that refer to this License, so
  that they refer to the ordinary GNU General Public License, version 2,
  instead of to this License.  (If a newer version than version 2 of the
  ordinary GNU General Public License has appeared, then you can specify
  that version instead if you wish.)  Do not make any other change in
  these notices.

    Once this change is made in a given copy, it is irreversible for
  that copy, so the ordinary GNU General Public License applies to all
  subsequent copies and derivative works made from that copy.

    This option is useful when you wish to copy part of the code of
  the Library into a program that is not a library.
