gcc commentary

Gcc has some humorous commentary built into it. I tried the datatype "long", and then tried "long long" and just for fun tried "long long long" and here's what it says:
    error: ‘long long long’ is too long for GCC

Curiously enough, gcc doesn't remark similarly for "short short". I expected it to say: error: 'short short' is too short for GCC!

Interesting.
