As of SWIG 1.3.40, the generated C/C++ wrapper will use the Tk Stubs

feature if compiled with <tt>-DUSE_TK_STUBS</tt>.
</p>
<p>
By default SWIG sets the minimum Tcl version to support to the 8.4
as that's the minimum Tcl version we aim to support (since SWIG 4.1.0; before
this SWIG set it to 8.1, which was the first Tcl version with the stubs
mechanism). This minimum version is passed to <tt>Tcl_InitStubs()</tt> and
<tt>Tk_InitStubs()</tt>. You can override with a specific version using
<tt>-DSWIG_TCL_STUBS_VERSION="8.5"</tt> or set it to the Tcl version being
compiled with using <tt>-DSWIG_TCL_STUBS_VERSION=TCL_VERSION</tt>.
