That's a good suggestion. I think this would be the first use of a 
compound literal in the code base so it would be helpful to mention that 
in the commit message.

We've been depending on C99 for a while now so I'd support adding this 
compound literal as a test balloon for compiler support. Ævar reported a 
while back that they are supported by IBM xlc, Oracle SunCC and HP/UX's 
aCC[1] and back then I looked at NonStop which seemed to offer support 
with the right compiler flag.

Overall this is a well written, well motivated patch with a good commit 
message.

Best Wishes

Phillip
