Does TCL 8.4.9 and above have support for receiving 64 bit pointers
through a TCL extension?

Values passed through Tcl typically are in the form of a Tcl_Obj struct.

If you write your own Tcl_ObjType, you can use the
internalRep.otherValuePtr field to pass through a (VOID *) value
easily.

Or, I imagine you could fairly easily pack/unpack your pointer value
in/out of a Tcl_NewByteArrayObj().
