They weren't C constants originally, they were Pascal
constants, and it made sense at the time given the way
the Pascal compiler they were using handled string
literals. They also worked okay as multi-character char
literals in the early C compilers used on the Mac.
It's unfortunate that gcc gets persnickety about those.

Is this another indication that we should have an
immutable version of the bytes type?
