* 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: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

	* generic/tcl.h:          add fixes for building on Leopard and support
	* unix/tclUnixPort.h:     for 64-bit CoreFoundation on Leopard.
	* macosx/tclMacOSXFCmd.c:

	* unix/tclUnixPort.h: on Darwin x86_64, disable use of vfork as it
	causes execve to fail intermittently. (rdar://4685553)

	* generic/tclTomMath.h: on Darwin 64-bit, for now disable use of 128-bit
	arithmetic through __attribute__ ((mode(TI))), as it leads to link
	errors due to missing fallbacks. (rdar://4685527)

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

	* macosx/Tcl.xcodeproj/default.pbxuser: add test suite target that runs
	* macosx/Tcl.xcodeproj/project.pbxproj: the tcl test suite at build time
	 and shows clickable test suite errors in the GUI build window.

	* tests/macOSXFCmd.test: fix use of deprecated resource fork paths.

	* unix/tclUnixInit.c (TclpInitLibraryPath): move code that is only
	needed when TCL_LIBRARY is defined to run only in that case.

	* generic/tclLink.c (LinkTraceProc): fix 64-bit signed-with-unsigned
	comparison warning from gcc4 -Wextra.
