	* unix/configure.in: removed SC_ENABLE_MEMDEBUG call
	* unix/tcl.m4: replaced SC_ENABLE_MEMDEBUG with a more intelligent
	SC_ENABLE_SYMBOLS that takes yes|no|mem|compile|all as options now.

2002-10-09  Kevin B. Kenny  <[e-mail]>

	* win/tclWinTime.c: Added code to set an exit handler that
	terminates the thread that calibrates the performance counter, so
	that the thread won't outlive unloading the Tcl DLL. [Tcl bug
	620735].

2002-10-09  Donal K. Fellows  <[e-mail]>

	* doc/binary.n: More clarification of [binary scan]'s behaviour.

2002-10-09  Daniel Steffen  <[e-mail]>

	* generic/tclIntDecls.h: fixed botched regen.

2002-10-09  Daniel Steffen  <[e-mail]>

	* generic/tclInt.decls: made TclSetPreInitScript() declaration
	generic as it is used on mac & aqua as well.
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c: regen.
	* generic/tclCompile.h: added prototype for TclCompileVariableCmd.

	* mac/tclMacPort.h: removed incorrect <fcntl.h> definitions
	and obsolete <stat.h> definitions.
	* mac/tclMacChan.c: removed obsolete GetOpenMode() and replaced 
	associated constants with the <fcntl.h> analogues (they existing
	defs were inconsistent with <fcntl.h> which was causing havoc when
	Tcl_GetOpenMode was used instead of private GetOpenMode).

	* mac/tclMacFCmd.c: removed GenerateUniqueName(), use equivalent
	(and identically named) routine from MoreFiles instead.

	* mac/tclMacLoad.c: CONSTification, fixes to Vince's last changes.

	* mac/tclMacFile.c: 
	* mac/tclMacTest.c:
	* mac/tclMacUnix.c: CONSTification.

	fix for missing autoname token from TclOSACompileCmd. (bdesgraupes)
	* mac/AppleScript.html(AppleScript delete): doc fix. (bdesgraupes)

	* mac/tcltkMacBuildSupport.sea.hqx: updated MoreFiles to 1.5.3, 
	updated build instructions for 8.4.
	* mac/tclMacProjects.sea.hqx: rebuilt archive.

2002-10-09  Donal K. Fellows  <[e-mail]>

	* doc/Alloc.3: Added a note to mention that attempting to allocate
	a zero-length block can return NULL.  [Tk bug 619544]

2002-10-04  Donal K. Fellows  <[e-mail]>

	* doc/binary.n: Doc improvements [Patch 616480]

	* tests/fCmd.test, tests/winFCmd.test:
	* tools/eolFix.tcl, tools/genStubs.tcl: [file exist] -> [file exists]
	Thanks to David Welton.

2002-10-03  Don Porter  <[e-mail]>

	* doc/tcltest.n: fixed typo [Bug 618018].  Thanks to "JJM".

2002-10-03  Donal K. Fellows  <[e-mail]>

	* tools/man2help2.tcl: 
	* tests/http.test, tests/httpd, tests/httpold.test: 
	* tests/env.test, tests/binary.test, tests/autoMkindex.test: 
	* library/init.tcl, library/http/http.tcl: [info exist] should
	really be [info exists].  [Bug 602566]

	* doc/lsearch.n: Better specification of what happens when -sorted
	is mixed with other options. [Bug 617816]

2002-10-01  Jeff Hobbs  <[e-mail]>

	* generic/tclProc.c (TclCreateProc): mask out VAR_UNDEFINED for
	precompiled locals to support 8.3 precompiled code.
	(Tcl_ProcObjCmd): correct 2002-09-26 fix to look for tclProcBodyType.

2002-10-01  Donal K. Fellows  <[e-mail]>

	* doc/socket.n: Mentioned that ports may be specified as serivce
	names as well as integers. [Bug 616843]

2002-09-30  Jeff Hobbs  <[e-mail]>

	* generic/tclCompCmds.c (TclCompileRegexpCmd): correct the
	checking for bad re's that didn't terminate the re string.
	Resultant compiles were correct, but much slower than necessary.

2002-09-29  David Gravereaux <[e-mail]>

	* win/tclAppInit.c: Added proper exiting conditions using Win32
	console signals.  This handles the existing lack of a Ctrl+C exit
	to call exit handlers when built for thread support.  Also, properly
	handles exits from other conditions such as CTRL_CLOSE_EVENT,
	CTRL_LOGOFF_EVENT, and CTRL_SHUTDOWN_EVENT signals.  In all cases,
	exit handlers will be called.  [Bug 219355]

	* win/makefile.vc: Added missing tclThreadAlloc.c to the build
	rules and defines USE_THREAD_ALLOC when TCL_THREADS is defined
	to get the new behavior by default.

2002-09-27  Don Porter  <[e-mail]>

	* README:		Bumped to version 8.4.1 to avoid confusion
	* generic/tcl.h:	of CVS snapshots with the actual 8.4.0

2002-09-26  Jeff Hobbs  <[e-mail]>

	* unix/configure: regen.
	* unix/tcl.m4: improve AIX-4/5 64bit compilation support.

	* generic/tclProc.c (Tcl_ProcObjCmd): correct overeager
	optimization of noop proc to handle the precompiled case. (sofer)

	* unix/ldAix (nmopts): add -X32_64 to make it work for 32 or 64bit
	mode compilation.

	* library/encoding/koi8-u.enc: removed extraneous spaces that
	confused encoding reader. [Bug #615115]

	* unix/Makefile.in: generate source dists with -src designator and
	do not generate .Z anymore (just .gz and .zip).

2002-09-18  Mumit Khan <[e-mail]>

	Added basic Cygwin support.

	* win/tcl.m4 (SC_PATH_TCLCONFIG): Support one-tree build.
	(SC_PATH_TKCONFIG): Likewise.
	(SC_PROG_TCLSH): Likewise.
	(SC_CONFIG_CFLAGS): Assume real Cygwin port and remove -mno-cygwin 
	flags.  Add -mwin32 to extra_cflags and extra_ldflags.
	Remove ``-e _WinMain@16'' from LDFLAGS_WINDOW.
	* win/configure.in: Allow Cygwin build.
	(SEH test): Define to be 1 instead of empty value.
	(EXCEPTION_DISPOSITION): Add test.
	* win/configure: Regenerate.

	* generic/tcl.h: Don't explicitly define __WIN32__ for Cygwin, let
	the user decide whether to use Windows or POSIX personality.
	(TCL_WIDE_INT_TYPE, TCL_LL_MODIFIER, struct Tcl_StatBuf): Define
	for Cygwin.
	* generic/tclEnv.c (Tcl_CygwinPutenv): putenv replacement for
	Cygwin.
	* generic/tclFileName.c (Tcl_TranslateFileName): Convert POSIX 
	to native format.
	(TclDoGlob): Likewise.
	* generic/tclPlatDecls.h (TCHAR): Define for Cygwin.
	* win/tclWinPort.h (putenv, TclpSysAlloc, TclpSysFree, 
	TclpSysRealloc): Define for Cygwin.

2002-09-26  Daniel Steffen  <[e-mail]>

	* macosx/Makefile: preserve environment value of INSTALL_ROOT.
	When embedding only use deployment build. Force relink before
	embedded build to ensure new linker flags are picked up.

	* macosx/Tcl.pbproj/project.pbxproj: add symbolic links to
	debug lib, stub libs and tclConfig.sh in framework toplevel.
	Configure target dependency fix. Fix to 'clean' action. Added
	private tcl headers to framework. Install tclsh symbolic link.
	Html doc build works when no installed tclsh available. Made
	html doc structure in framework more like in Apple frameworks.

2002-09-24  Donal K. Fellows  <[e-mail]>

	* unix/tcl.m4 (SC_TCL_64BIT_FLAGS): Yet more robust 64-bit value
	detection to close [Bug 613117] on more systems.

	* generic/tclCompile.c (TclPrintSource): More CONSTifying.
	* generic/tclExecute.c (EvalStatsCmd): Object-ify to reduce
	warnings.  Thanks to 'CoderX2' on the chat for bringing this to my
	attention...

	* unix/tcl.m4: Forgot to define TCL_WIDE_INT_IS_LONG at the
	appropriate moment.  I believe this is the cause of [Bug 613117]

	* doc/lset.n: Changed 'list' to 'varName' for consistency with
	lappend documentation.  Thanks to Glenn Jackman [Bug 611719]

2002-09-22  Don Porter  <[e-mail]>

	* library/tcltest/tcltest.tcl:  Corrected [puts -nonewline] within
	test bodies.  Thanks to Harald Kirsch.  [Bug 612786, Patch 612788]
	Also corrected reporting of body return code.  Thanks to David
	Taback [Bug 611922]
	* library/tcltest/pkgIndex.tcl: Bump to version 2.2.1.
	* tests/tcltest.test: added tests for these bugs.

2002-09-15  Mo DeJong  <[e-mail]>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Add PEEK_XCLOSEIM
	define under Linux. This is used by Tk to double
	check that an X input context is cleaned up
	before it is closed.

2002-09-12  David Gravereaux <[e-mail]>

	* win/coffbase.txt: Added BLT to the virtual base address
	listings table should BLT's build tools decide to use it.

2002-09-12  Daniel Steffen  <[e-mail]>

	* generic/tcl.h:
	* mac/tclMacApplication.r:
	* mac/tclMacLibrary.r:
	* mac/tclMacResource.r: unified use of the two equivalent 
	resource compiler header inclusion defines RC_INVOKED and
	RESOURCE_INCLUDED, now use RC_INVOKED throughout. 

2002-09-10  Mo DeJong  <[e-mail]>

	* unix/README: Add note about building extensions
	with the same compiler Tcl was built with.
	[Tk Bug 592096]

2002-09-10  Daniel Steffen  <[e-mail]>

	* macosx/Tcl.pbproj/project.pbxproj: disabled building html
	documentation during embedded build.

2002-09-10  Daniel Steffen  <[e-mail]>

	* unix/Makefile.in: added DYLIB_INSTALL_DIR variable for macosx
	and set it to default value ${LIB_RUNTIME_DIR}
	* unix/tcl.m4 (Darwin): use DYLIB_INSTALL_DIR instead of
	LIB_RUNTIME_DIR in the -install_name argument to ld.
	* unix/configure: regen.

	* macosx/Tcl.pbproj/project.pbxproj:
	* macosx/Makefile: added support for building Tcl as an embedded
	framework, i.e. using an dyld install_name containing
	@executable_path/../Frameworks via the new DYLIB_INSTALL_DIR
	unix/Makefile variable.

	Hemang Lavana for the fix.  [Bug 604609]
