tkinter.c now includes <tclInt.h>. I don't seem to have this file, even though I installed Tcl/Tk 8.4.1. Thus, the tkinter won't build. How can this be?

On SuSE, it is installed as part of the tcl-devel package. It is an internal header, though, so it appears not to be universally available.

I need it to implement the type checks, as it declares symbols like tclBooleanType. Unfortunately, Tcl developers appear to consider this symbol internal.

Fortunately, they offer a lookup-by-name operation to find types, which is now used in _tkinter.c 1.133. For efficiency, I cache the lookup of the relevant types.
