Out of interest (and not in any way trying to sound snide) do you know

although I'm much less familiar with those.

No...honestly I never really paid much attention to the issue until now. And I don't think you sounded snide...it's a perfectly reasonable question.

I do know that I don't recall my C++ code generating "this variable is unassigned" errors, but that's probably due to the lack of *any* checking as opposed to more correct checking.

VC++ also has some basic checking. But in the case of the sample of valentin t. the C++ compiler simply doesn't warn anymore.
That doesn't mean that the C++ is much better in detection, but simply turns of the warning if it can't detect the usage of uninitialized variables anymore.
