Actually, I'm seriously considering getting rid of uninitialized_var().
The thing is an abomination, and we've already had one bug due to it
(real uninitialized variable that was incorrectly hidden by
The thing is moronic. The whole thing is almost entirely due to
compiler bugs (*stupid* gcc behavior), and we would have been better
off with an explicit (unnecessary) initialization that at least
doesn't cause random crashes etc if it turns out to be wrong.
So please don't use that abortion. Just initialize things to
0/NULL/whatever if gcc complains and you want to get rid of them.
Better than the crap that is uninitialized_var(), which just causes
silent random behavior if it is wrong.
