J.C., Please stop harrassing people who, unlike you, are trying to contribute to making GCC better. You were safe to ignore when you were merely annoying. If you start driving contributors away, that will be a more serious problem.
Alexey and everyone else, It's best to ignore J.C. Pizarro. He's an attention-seeking troll, who has just enough technical knowledge to derail conversation. His technical objections carry no weight with anyone but himself. No one who is proposing a contribution to GCC should bother trying to refute any objection J.C. Pizarro raises. If, like a stopped clock that is right twice a day, he's accidentally right about something, someone else will raise the issue.
