--- Comment #2 from Reid Kleckner <rnk at google.com> ---
r340079. I'll merge it to 7.0, since I can easily imagine people will start
trying out ThinLTO sooner than later if we finish it in Chromium.

> What mangled names does MSVC generate in these cases?

We used to emit "?A@" for these, MSVC emits "?A0x1234ABCD@" for them, and now
we do the same. Undname ignores whatever is between the 'A' and the '@'.
