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.
