* macosx/tkMacOSXDebug.c: add TkMacOSXGetNamedDebugSymbol() function

	* macosx/tkMacOSXDebug.h: that finds unexported symbols in loaded
	libraries by manually walking their symbol table; only to be used for
	debugging purposes, may break unexpectedly in the future. Needed to get
	access to private_extern internal debugging functions in HIToolbox.

	* macosx/tkMacOSXCarbonEvents.c: fix debug event tracing on Tiger.
	* macosx/tkMacOSXMenu.c: add debug menu printing during reconfigure.
	* macosx/tkMacOSXInit.c: conditionalize 64bit-unsafe dyld code.
	* macosx/GNUmakefile: add 'wish8.x' symlink to SYMROOT.

	* macosx/Wish.xcode/project.pbxproj:     fix copy to tktest resource
	* macosx/Wish.xcodeproj/project.pbxproj: fork when zerolinked.

	* macosx/Wish.xcode/default.pbxuser:     add widget demo as argument to
	* macosx/Wish.xcodeproj/default.pbxuser: executables (on by default).

	* unix/configure:    add caching, use AC_CACHE_CHECK instead of
	* unix/configure.in: AC_CACHE_VAL where possible, consistent message
	* unix/tcl.m4:       quoting, sync relevant tclconfig/tcl.m4 changes and
	gratuitous formatting differences, fix SC_CONFIG_MANPAGES with default
	argument, Darwin improvements to SC_LOAD_*CONFIG.
