Cygwin's Tcl/Tk is essentially frozen at 8.4.1. However, I really 
believe the problem is that the Tcl/Tk is not a full Cygwin application: 
it is mostly Windows, with only a few pieces converted to Posix through 
the cygwin.dll, so many things don't quite work correctly. For instance, 
the current gitk works fine under a pure Cygwin build of Tcl/Tk (8.4.13) 
I have locally. So, I believe the commit message I wrote is correct.
