Why? There are many ways to alleviate this. Doing some warnings in the
front-ends, such LLVM does is one. Or propagate some "uninitialized" bit, that
can checked later. Or something that hasn't invented yet. It is clear that
other compilers can get this right, so GCC could, if someone had the time and
interest.
