* thread.cc (pthread_key::run_destructor): Run_destructor is not
       const as it needs to set the key value.
       * thread.h (pthread_key::run_destructor): Ditto.

2002-09-27  Robert Collins <rbtcollins@hotmail.com>

       * thread.cc (pthread_key::run_destructor): Follow opengroup algorithm.
       I.e. only run the destructor NON-NULL key values, and reset the key
       to NULL before running the destructor. Reported by Thomas Pfaff.
