To address the Subject line first, a statement is NEVER an expression in C.

This is an interesting construct, but it's not legal C. Probably some
compiler writer's bright idea.

When you feed a compiler something that it considers gibberish, it's
fairly normal for the error messages to be a bit cryptic.
