@AdamChalcraft gcc uses the same register for the first function parameter and the return value if they're both int. So yes, it's a golf hack to simply assign the return value to the first parameter.

I believe you can use a^c (bitwise xor) to check for equality which is shorter than c==a. Note that you'd have to flip the other parts of the ternary.
