- *   04/04/2010
- *   - Initial version, written by Aleric Inglewood @ SL
- *
- *   10/11/2010
- *   - Added APR_HAS_THREADS #if's to allow creation and destruction
- *     of subpools by threads other than the parent pool owner.
- *
- *   05/02/2011
- *   - Fixed compilation on windows: Suppress compile warning 4996
- *     and include <winsock2.h> before including <ws2tcpip.h>,
- *     by Merov Linden @ SL.
