	cygwin         : ChangeLog dcrt0.cc mount.cc ntdll.h shared.cc 
	                 shared_info.h spinlock.h syscalls.cc 

Log message:
	* shared_info.h (user_info): Add dll_crt0_1 as a friend.
	(user_info::version): Make LONG to accommodate spinlock use.
	(user_info::create): New static function renamed from user_info_create.
	(user_info::initialize): New private function renamed from
	user_info_initialize.
	(SHARED_VERSION): Delete.
	(SHARED_VERSION_MAGIC): Ditto.
	(USER_VERSION_MAGIC): Ditto.
	(SHARED_INFO_CB): Ditto.
	(USER_VERSION): Ditto.
	(USER_VERSION_MAGIC): Ditto.
	(CURR_SHARED_MAGIC): Update.
	(CURR_USER_MAGIC): Ditto.
	(shared_info::version): Make LONG to accommodate spinlock use.
	(shared_info::create): New static function mirroring user_info::create.
	(dll_crt0_1): Accommodate change to user_info::initialize.
	* spinlock.h (spinlock::setto): New variable member.
	(spinlock::done): New function.
	(spinlock::spinlock): Generalize to allow arbitrary values and timeouts.  Call
	done() when lock is not needed.
	* ntdll.h: Make multiple-inclusion safe.
	(NtQuerySystemTime): Declare.
	* shared.cc (installation_root_inited): Rename from shared_mem_inited.
	(init_installation_root): Make inline.  Use a spinlock to ensure that this is
	initialized only once per session.
	(user_info::initialize): Rename from user_shared_initialize.  Protect with
	spinlock on sversion and remove other spinlock-like things.  Remove reference
	to user_shared since it is now implicit.  Refer to spinlock version of
	multiple_cygwin_problem to ensure that any spinlock is released.
	(user_info::create): Rename from user_shared_create.  Accommodate change from
	user_shared_initialize to user_info::initialize.
	(shared_info::create): New inline function.
	(shared_info::initialize): Protect with spinlock on sversion.  Move heap_init
	back under specific control of shared_info spinlock.  Remove reference to
	SHARED_INFO_CB and just use sizeof(*this).
	(memory_init): Move all locking into respective functions where it is needed.
	Accommodate name changes.  Remove call to heap_init().
	* syscalls.cc (seteuid32): Accommodate name change to user_info::create().
	* mount.cc (mount_info::create_root_entry): Report on errors from add_item
	since they should be nonexistent.
	(mount_info::init): Don't initialize nmounts.  It should already be zero.  Give
	more verbose error when root_idx < 0.  Implicitly use this pointer rather than
	explicitly referencing mount_table->.
	(mount_info::add_item): Minor whitespace fix.
