Which, in that scope, is defined as a C++ symbol. Which is why it
didn't match the C __errno_location in libpthread.
The "d'oh" here is that the clue was in the title: it wouldn't have said
"(void)" if it was trying to match a C symbol because it wouldn't have

Oh well, we learn. (And good spot, Claudio!)
