Browse Source 
2009-02-06  Benjamin Kosnik  <bkoz@redhat.com>

	* include/std/thread (thread::id): Move definition inside thread.
	Use native_handle_type. Remove this_thread::get_id friend.
	Change __thread_data_ptr to __shared_base_ptr.
	(thread:🆔:id(native_handle_type): Make public. Still explicit.
	Use native_handle_type. Change _M_thread_id to _M_thread.
	(thread::__thread_data_base): Rename to _Impl_base. Use id, change
	_M_thread_handle to _M_id.
	(thread::__thread_data): Rename to _Impl.
	Fixup for renames.
	(thread::_M_make_thread_data): Return derived type.
	(thread::hardware_concurrency): Add definition for default case.
	(thread::get_id): Now can define inline.
	(thread): Change _M_thread_data to _M_data.
	(this_thread::get_id): Now can define inline.
	* src/thread.cc (__thread_proxy): Rename to
	execute_native_thread_routine.
	Fixup for other renames.
	* testsuite/30_threads/thread/cons/assign_neg.cc: New.
	* testsuite/30_threads/thread/cons/copy_neg.cc: New.
