Sections of code which are guarded by#ifdef TK_AQUA were committed incb85244. But from examining the CPython
and Tcl/Tk repository histories, it appears nothing has ever defined this macro. (Tk Aqua itself instead defines/uses theMAC_OSX_TK macro.) The only mentions of it I found elsewhere were as-DTK_AQUA passed to build commands, either in a Setup.local file (https://mail.python.org/pipermail/pythonmac-sig/2001-December/004553.html,https://mail.python.org/pipermail/pythonmac-sig/2002-November/006746.html) or manual command line invocation (https://mail.python.org/pipermail/pythonmac-sig/2002-January/004776.html).

So I believe this code has long been unused, and I suspect that trying to use it now is not a good idea. Can it be removed?
