* unix/tcl.m4 (Darwin): add support for --enable-64bit on x86_64, for

	universal builds including x86_64, for 64-bit CoreFoundation on Leopard
	and for use of -mmacosx-version-min instead of MACOSX_DEPLOYMENT_TARGET.
	* unix/configure.in (Darwin): remove 64-bit arch flags from CFLAGS for
	combined 32-bit and 64-bit universal builds, as neither TkAqua nor TkX11
	can be built for 64-bit at present.
	* unix/configure: autoconf-2.59
	* unix/tkConfig.h.in: autoheader-2.59

	* macosx/Wish.xcodeproj/project.pbxproj: switch native release targets
	to use DWARF with dSYM, Xcode 3.0 changes.
	* macosx/README: updates for x86_64 and Xcode 2.3.

	* macosx/tkMacOSXInit.c (TkpInit): when available, use public
	TransformProcessType() API instead of CPSEnableForegroundOperation() SPI
	to notify the window server that we are a GUI application.

	* macosx/tkMacOSXWm.c (WmAttrGetTitlePath): use HIWindow API on >=Tiger.

	* macosx/tkMacOSXMouseEvent.c (GenerateToolbarButtonEvent):
	* macosx/tkMacOSXMenus.c (GenerateEditEvent):
	* macosx/tkMacOSXMenu.c (MenuSelectEvent): bzero XVirtualEvent structure
	before use to ensure all fields are initialized. [Bug 1542205]
