* unix/tcl.m4 (Darwin): add 64bit support, check for Tiger copyfile(),

	add CFLAGS to SHLIB_LD to support passing -isysroot in env(CFLAGS) to
	configure (flag can't be present twice, so can't be in both CFLAGS and
	LDFLAGS during configure), don't use -prebind when deploying on 10.4,
	define TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING (rdar://3171542).
	(SC_ENABLE_LANGINFO, SC_TIME_HANDLER): add/fix caching, fix obsolete
	autoconf macros. Sync with tk/unix/tcl.m4.

	* unix/configure.in: fix obsolete autoconf macros, sync gratuitous
	formatting/ordering differences with tk/unix/configure.in.

	* unix/Makefile.in: add CFLAGS to tclsh/tcltest link to make executable
	linking the same as during configure (needed to avoid loosing any linker
	relevant flags in CFLAGS, in particular flags that can't be in LDFLAGS).
	Avoid concurrent linking of tclsh and compiling of tclTestInit.o or
	xtTestInit.o during parallel make.
	(checkstubs, checkdoc, checkexports): dependency and Darwin fixes
	(dist): add new macosx files.

	* unix/tclLoadDyld.c (TclpDlopen): use NSADDIMAGE_OPTION_WITH_SEARCHING
	on second NSAddImage only. [Bug 1204237]
	(TclGuessPackageName): should not be MODULE_SCOPE.
	(TclpLoadMemory): ppc64 and endian (i386) fixes, add support for loading
	universal (fat) bundles from memory.

	* unix/tclUnixFCmd.c:
	* macosx/tclMacOSXFCmd.c: ppc64 and endian (i386) fixes.
	(TclMacOSXCopyFileAttributes): add support for new Tiger copyfile() API
	to enable copying of xattrs & ACLs by [file copy].

	* generic/tcl.h: add Darwin specifc configure overrides for TCL_WIDE
	defines to support fat compiles of ppc and ppc64 at the same time,
	(replaces Darwin CVS fix by emoy, rdar://3693001).
	add/correct location of version numbers in macosx files.

	* generic/tclInt.h: clarify fat compile comment.

	* unix/tclUnixPort.h: add Darwin specifc configure overrides to support
	fat compiles, where configure runs only once for multiple architectures
	(replaces Darwin CVS fix by emoy, rdar://3693001).

	* macosx/tclMacOSXBundle.c:
	* macosx/tclMacOSXNotify.c:
	* unix/tclUnixNotfy.c:
	* unix/tclUnixPort.h: fix #include order to support compile time
	override of HAVE_COREFOUNDATION in tclUnixPort.h when building for ppc64

	* macosx/Tcl.pbproj/default.pbxuser (new file):
	* macosx/Tcl.pbproj/jingham.pbxuser:
	* macosx/Tcl.pbproj/project.pbxproj:
	* macosx/Tcl.xcode/default.pbxuser (new file):
	* macosx/Tcl.xcode/project.pbxproj (new file):
	* macosx/Tcl.xcodeproj/default.pbxuser (new file):
	* macosx/Tcl.xcodeproj/project.pbxproj (new file): new/updated projects
	for Xcode 2.2 on 10.4, Xcode 1.5 on 10.3 & ProjectBuilder on 10.2, with
	native tcltest targets and support for universal (fat) compiles.

	* macosx/README: clarification/cleanup, document new Xcode projects and
	universal (fat) builds via CFLAGS (i.e. all of ppc ppc64 i386 at once).

	* unix/Makefile.in:
	* unix/aclocal.m4:
	* unix/configure.in:
	* unix/dltest/Makefile.in:
	* macosx/configure.ac (new file): add support for inclusion of
	unix/configure.in by macosx/configure.ac, allows generation of a config
	headers enabled configure script in macosx (required by Xcode projects).

	* macosx/GNUmakefile: rename from Makefile to avoid overwriting by
	configure run in tcl/macosx, add support for reusing configure cache,
	build target fixes, remove GENERIC_FLAGS override now handled by tcl.m4.

	* generic/tcl.decls: add Tcl_Main declaration as comment to avoid
	'checkstubs' target complaining about it missing from stubs.

	* generic/regex.h:
	* generic/tclDate.c:
	* generic/tclEnv.c:
	* generic/tclGetDate.y:
	* generic/tclIOUtil.c:
	* generic/tclObj.c:
	* generic/tclStubInit.c:
	* generic/tclStubLib.c:
	* generic/tclPathObj.c:
	* generic/tclThreadAlloc.c:
	* generic/tclThreadStorage.c:
	* generic/tclTrace.c:
	* generic/tclVar.c:
	* generic/tommath.h:
	* tools/fix_tommath_h.tcl:
	* unix/tclUnixFCmd.c: ensure externally visible symbols not contained in
	stubs table are declared as MODULE_SCOPE (or as static if not used
	outside of own source file). These changes allow 'make checkstubs' to
	complete without error on Darwin with gcc 4.

	* generic/rege_dfa.c (getvacant):
	* generic/regexec.c (cfind):
	* generic/tclCompExpr.c (CompileSubExpr):
	* generic/tclNamesp.c (NamespaceEnsembleCmd):
	* unix/tclUnixChan.c (TclUnixWaitForFile): initialise variables to
	silence gcc 4 warnings.

	* generic/tclExecute.c (TclExecuteByteCode): fix unused variable warning
	when NO_WIDE_TYPE is defined.

	* generic/regguts.h: only #define NDEBUG if not already #defined.

	* unix/tclUnixNotfy.c:
	* macosx/tclMacOSXNotify.c: sync whitespace & comments.

	* unix/tclUnixPort.h:
	* win/tclWinPort.h: remove declaration of obsolete&unused TclpMutex API.

	* unix/configure:
	* unix/tclConfig.h.in: regen.
