No, sorry, but now.  Converting all affected functions to static
functions just because this might be null is much too intrusive for my
taste.  *If* that's really a problem going forward, I'd rather see the
pointer test moved into the caller.  But don't waste your time on a
patch yet.
 
Let's please take a step back and look at what happens.  So, here's the
question:  What error message does G++ 6 generate in case of an `if
(this)' test in a member function, and why on earth should it care and
do that?
