And this is why I hate macros.

Hmm, v8 seems to have run into something similar, and they suggest changing the client code instead of silencing the warning. Unfortunately, the relevant client code is something we don't have much control over.

We might be able to work around it by putting the relevant sections in extern "C" blocks if this only happens when compiling C++

[Sam Spilsbury (smspillaz)]

Hmm, nope, upon checking the error again it happens when compiling C too.

The problem is that this is not a standard compiler flag that we are tripping over, -Wno-unused-local-typedefs is not supported in clang or earlier versions of gcc. So we might have to add some nasty compiler detection :(

I've filed the relevant bug against glib here: https://bugzilla.gnome.org/show_bug.cgi?id=691107
