I'm pretty sure that's a gcc-ism, not standard C.
Hmm, after some digging: the feature is called compound literals and it was
introduced in c99 although gcc has support in c90. To disable this support it's
needed a flag -pedantic. Sorry.
The real question is do we want to. What's your use-case for this?
Just do not have a hardcoded values. It is too easy to make a mistake in
hardcoded value.
