+// Change Log:
+// 6 Jun 01
+// WEKEMPF Initial version.
+// 30 May 02 WEKEMPF
+// Added interface to set specific cleanup handlers.
+// Removed TLS slot limits from most implementations.
+// 22 Mar 04 GlassfordM for WEKEMPF
+// Fixed: thread_specific_ptr::reset() doesn't check error returned
+// by tss::set(); tss::set() now throws if it fails.
+// Fixed: calling thread_specific_ptr::reset() or
+// thread_specific_ptr::release() causes double-delete: once on
+// reset()/release() and once on ~thread_specific_ptr().
