* macosx/tkMacOSXWm.c (WmAttributesCmd, WmIconbitmapCmd): add support

	for weakly importing symbols not available on OSX 10.2 or 10.3, enables
	binaires built on later OSX versions to run on earlier ones.
	* macosx/README: document how to enable weak-linking; cleanup.
	* unix/configure.in: enforce requirement of OSX 10.2 for TkAqua; move
	* unix/tcl.m4:       Darwin specific checks & defines that are only
	relevant to the tcl build out of tcl.m4; restrict framework option to
	Darwin; cleanup quoting.
	* unix/configure: autoconf-2.13

	* macosx/tkMacOSXKeyEvent.c: ifdef out diagnostic messages to stderr.

	* macosx/tkMacOSXEvent.h:      standardize MAC_OS_X_VERSION_MAX_ALLOWED
	* macosx/tkMacOSXMenu.c:       checks per QA1316, ensure define can be
	* macosx/tkMacOSXMenubutton.c: overriden on command line (from default
	* macosx/tkMacOSXMenus.c:      of current OS version).
	* macosx/tkMacOSXMouseEvent.c:
	* macosx/tkMacOSXWm.c:
