* generic/tclInt.h: Reworked the Tcl header files into a clean
* unix/tclUnixPort.h: hierarchy where tcl.h < tclPort.h < tclInt.h
* win/tclWinInt.h: and every C source file should #include
* win/tclWinPort.h: at most one of those files to satisfy its
declaration needs. tclWinInt.h and tclWinPort.h also better organized
so that tclWinPort.h includes the Windows implementation of
cross-platform declarations, while tclWinInt.h makes declarations that
are available on Windows only.
* generic/tclBinary.c (TCL_NO_MATH): Deleted the generic/tclMath.h
* generic/tclMath.h (removed): header file. The internal Tcl
* macosx/Makefile (PRIVATE_HEADERS): header, tclInt.h, has a
* win/tcl.dsp: #include <math.h> directly,
and file external to Tcl needing libm should do the same.
* win/Makefile.in (WIN_OBJS): Deleted the win/tclWinMtherr.c file.
* win/makefile.bc (TCLOBJS): It's a vestige from matherr() days
* win/makefile.vc (TCLOBJS): gone by.
* win/tcl.dsp:
* win/tclWinMtherr.c (removed):

* win/tclWinInit.c: recognize Windows CE as a Win platform.
This just recognizes CE - full support will come later.

* win/Makefile.in:
* win/tclWinInt.h:
* win/tclWinThrd.c: added new threaded allocator contributed by
AOL that significantly reduces lock contention when multiple
threads are in use. Only Windows and Unix implementations are
ready, and the Windows one may need work. It is only used by
default on Unix for now, and requires that USE_THREAD_ALLOC be
defined (--enable-threads on Unix will define this).

the internal platform specific stub table.
* win/tclWinFile.c (TclpObjStat): Now added the call to
'TclWinFlushDirtyChannels' to this function. I don't know where
my head was last thursday (2001-09-06), but the call was
actually added to 'TclpObjChdir', i.e. the implementation of
[cd]. Corrected this now. Thanks to Vince Darley for spotting
this.

80x performance hit for file I/O on Win* systems. On my system
it was closer to a 120x hit. Problem report by Uwe Traum <no
email address available>.
The fix goes like this: The obstacle is 'FlushFileBuffers',
executed whenever Tcl writes data to the OS, as Tcl has to wait
for the disk to complete I/O, and disks are slow. We remove that
obstacle. This opens another problem, [file size] reports back
wrong numbers. So for [file size] we add the call back in. As
optimization we keep track of the channels which were written to
and flush only these.
* win/tclWinFile.c (TclpObjStat): Added a call to
'TclWinFlushDirtyChannels'. This ensures that [file size] and
related commands report the correct size of a file even if Tcl
has recently written to it. Unixoid OS's always report the
correct size even for files with pending data, but Win*
syssystem don't. They only report what is actually on disk.
* win/tclWinInt.h: Added declaration of
'TclWinFlushDirtyChannels', making it available to other parts
of the tcl core.
* win/tclWinChan.c (TclWinFlushDirtyChannels): New, internal,
procedure. Goes through the list of open file channels and
forces the OS to flush its file buffers for all which were
written to since the last call of this function. This is an
expensive operation as Tcl has to wait for the OS to complete
actual writes to the disk.
(FileInfo): Added dirty flag required by the procedure above.
(FileOutputProc): Removed flushing of file buffers, setting the
dirty flag instead. This means that the previously incurred
delays do not happen anymore.
(TclWinOpenFileChannel): Added initialization of 'dirty' flag.
