* macosx/tkMacOSXInit.c:

* macosx/tkMacOSXNotify.c: introduction of new tcl notifier based on CFRunLoop allows replacement of the custom TkAqua notifier by a standard tcl event source. Removes requirement of threaded tcl core for TkAqua, allows to stub-link TkAqua against Tcl by removing use of the unstubbed TclInitNotifier & TclFinalizeNotifier. [Tcl Patch 1202052] * macosx/Wish.pbproj/project.pbxproj: stub-link TkAqua: build with USE_TCL_STUBS and link against libtclstub instead of Tcl.framework, unexport libtclstub symbols from Tk to avoid duplicate symbol warnings when linking with both Tcl and Tk, fixes for gcc4.0 warnings. * macosx/tkMacOSXBitmap.c: * macosx/tkMacOSXButton.c: * macosx/tkMacOSXDialog.c: * macosx/tkMacOSXFont.c: * macosx/tkMacOSXHLEvents.c: * macosx/tkMacOSXInit.c: * macosx/tkMacOSXKeyboard.c: * macosx/tkMacOSXMenu.c: * macosx/tkMacOSXMenubutton.c: * macosx/tkMacOSXWm.c: * macosx/tkMacOSXXStubs.c: fixed gcc 4.0 warnings. * unix/tcl.m4: sync with tcl * unix/configure: autoconf-2.13
