but I can't see why it shouldn't work in principle.

is replaced by Togl_CreateWindow(), a function that gets registered in Tk as a callback for window creation. In Tk/Tk 8.4a3, there is a new public API call
Tk_SetClassProcs() to register this callback, but for earlier versions of Tk

the binary will only work for Tcl/Tk 8.1-8.4a2.
The tk8.4a3 public headers (tk8.4a3.h + tkDecls.h) are included for
