+	* unix/configure:        Removing support for the hacky nonportable stack
+	* unix/configure.in:     check: it is not needed anymore, Tcl is very

+ * Questions include:
+ *   (1) How is the objc/objv tailcall to be run? My current thinking is that
+ *       it should essentially be
+ *           [tailcall a b c] <=> [uplevel 1 [list a b c]]
+ *       with two caveats
+ *            (a) the current frame is dropped first, after running all
+ *                pending cleanup tasks and saving its namespace
+ *            (b) 'a' is looked up in the returning frame's namespace, but the 
+ *                command is run in the context to which we are returning
+ *       Current implementation does this if [tailcall] is called from within
+ *       a proc, panics otherwise-
+ *   (2) Should a tailcall bypass [catch] in the returning frame? Current
+ *       implementation does not - it causes an error.
+ *
+ * FIXME!
