Comment (by Bryan Kadzban):
OK, I can get rid of the reference to Tcl_CloseObjCmd by calling a public
function that will return the pointer to that function (and then storing
it away) right before the Expect code that registers its own function to
handle Tcl "close" commands. (This is wrong -- Expect should be putting
its code in its own namespace, IMO -- but they can't do that now that
they've already released so many versions that have their "close" in the
root namespace. That's unfortunate, but not something we can do anything
about.)
Tcl_ReturnObjCmd is different -- the Expect handler that uses this
function isn't an override of a builtin Tcl command. But it calls into
the private Tcl function anyway, because it wants to use that
implementation of "return". That's fairly easy to fix, though: just call
Tcl_GetCommandInfo("return") (to get the info on Tcl's "return" command),
then call the function given by that function.
Patch is attached. This can probably be merged into the existing Expect
spawn patch, since it touches the same file. With this patch (and the
munging of tclUnixPort.h from Tcl, and after adding the include of
tclInt.h instead of tcl.h), Expect compiles successfully. I have not
tried running any testsuites with it yet, though.
