build works again.
* generic/tclInt.decls: Changes to the tests for
* generic/tclIntPlatDecls.h: clock frequency in Tcl_WinTime
* generic/tclStubInit.c: so that any clock frequency
* tests/platform.test (platform-1.3): is accepted provided that
* win/tclWin32Dll.c (TclWinCPUID): all CPU's in the system share
* win/tclWinTest.c (TestwincpuidCmd): a common chip, and hence,
* win/tclWinTime.c (Tcl_GetTime): presumably, a common clock. This
change necessitated a small burst of assembly code to read CPU ID
information, which was added as TclWinCPUID in the internal Stubs. To
test this code in the common case of a single-processor machine, a
'testwincpuid' command was added to tclWinTest.c, and a test case in
platform.test. Thanks to Jeff Godfrey and Richard Suchenwirth for
reporting this bug. [Bug #976722]

* generic/tclIntPlatDecls.h: places where it appeared before the
* unix/tclUnixPort.h changes of 14 May, because use of
* unix/tclUnixTime.h native time_t in its place requires
* win/tclWinTime.h: the 8.5 header reforms. [Bug #955146]

* generic/tclInt.decls: Promoted TclpLocaltime and TclpGmtime
* generic/tclIntDecls.h: from Unix-specific stubs to the generic
* generic/tclIntPlatDecls.h: internal Stubs table. Reran 'genstubs'
* generic/tclStubInit.c:
* unix/tclUnixPort.h:
* generic/tclClock.c: Changed a buggy 'GMT' timezone specification
to the correct 'GMT0'. [Bug #922848]
* unix/tclUnixThrd.c: Moved TclpGmtime and TclpLocaltime to
unix/tclUnixTime.c where they belong.
* unix/tclUnixTime.c (TclpGmtime, TclpLocaltime, TclpGetTimeZone,
ThreadSafeGMTime [removed],
ThreadSafeLocalTime [removed],
SetTZIfNecessary, CleanupMemory):
Restructured to make sure that the same mutex protects
all calls to localtime, gmtime, and tzset. Added a check
in front of those calls to make sure that the TZ env var
hasn't changed since the last call to tzset, and repeat
tzset if necessary. [Bug #942078] Removed a buggy test
of the Daylight Saving Time information in 'gettimeofday'
in favor of applying 'localtime' to a known value.
[Bug #922848]
* tests/clock.test (clock-3.14): Added test to make sure that
changes to $env(TZ) take effect immediately.
* win/tclWinTime.c (TclpLocaltime, TclpGmtime):
Added porting layer for 'localtime' and 'gmtime' calls.

leaps of the performance counter. See the MSDN Knowledge Base article
Q274323 for the hardware problem that makes this necessary on certain
machines.
* tests/winTime.test: Revised winTime-2.1 - it had a tolerance of
thousands of seconds, rather than milliseconds. (What's six orders of
magnitude among friends?
Both the above changes are triggered by a problem reported at
http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/1536811
although the developers find it difficult to believe that it accounts
for the observed behavior and suspect a fault in the RTC chip.

* win/configure.in: Add test that checks to
see if the compiler can cast to a union type.
* win/tclWinTime.c: Squelch compiler warning
about union initializer by casting to union
type when compiling with gcc.

* win/tclWinPipe.c:
* win/tclWinSerial.c:
* win/tclWinSock.c:
* win/tclWinThrd.c:
* win/tclWinTime.c: General cleanup of all worker threads used
by the channel drivers. Eliminates the normal case where the
worker thread is terminated ('cept the winsock one). Instead,
use kernel events to signal a clean exit. Only when the worker
thread is blocked on an I/O call is the thread terminated.
Essentially, this makes all other channel worker threads behave
like the PipeReaderThread() function for it's cleaner exit
behavior. This appears to fix [Bug 597924] but needs 3rd party
confirmation to close the issue.
