// Attempt to reduce ifdef soup within the larger code files by blanking out
// or swapping these specialized functions.
// I'm not being super smart about this: if usage of a function leads to a
// compile error just adjust this as necessary. This is a bit less typing than
// leaving the header empty and redefining everything in the .c file, but if
// the balance changes we should switch to always doing that.
