--- Comment #3 from Czcibor Bohusz-Dobosz czbd@o2.pl --- Weird - I have just now built the preceding commit, just to make sure, and it also suffers from the same issue. I've also noticed that, for some reason, several sources in the wine directory have been untracked (they definitely weren't this way before the bisecting)...
So, apologies - looks like my git somehow got borked? Gotta bisect this one again...
