It all happened after Sabayon bug 2699, and I am still laughing so hard.
Everybody in Italy knows at least two things: who is Silvio Berlusconi and what is the first weekday. I cannot guarantee on the rest, though.
But of course, glibc asserts that the second pillar of the Italian knowledge is just… wrong. For it and Ulrich Drepper the first weekday is Sunday and no matter what the fuck you think, say, write: as long as you don’t have the proof of it being Monday, you will live with the bug.
It seems that drepper has more power than our Prime Minister and his escorts all together when it’s about picking the first weekday! woot!
