I have read the rule that enforces "this->" dereferencing - for the sake of
resolving ambiguity. There is no ambiguity in the above declaration though.

The struct variable/pointer variable declaration declares two variables at
once, where the latter can be changed whenever seen fit. I can't see why it
shouldn't make sense (but I may add to my defense that I haven't written that
code and never would have written code like that: It is my ungrateful task to
make it fit for gcc 4). Anyway, gcc 4 is the only compiler we found yet to
reject this code. Well, stuff like that shouldn't appear to often, so we can
manually fix it.
