<div>
<pre>using Foo=int;
int i;
int main(){
using Foo=char; // <== clang doesn't warn about this, gcc does
int i;
}
gcc catches both: <a href="https://godbolt.org/g/6heXBO">https://godbolt.org/g/6heXBO</a>
clang 3.8 doesn't warn on the shadowed 'using': <a href="https://godbolt.org/g/zTgIDn">https://godbolt.org/g/zTgIDn</a>
Tested with every version of clang on godbolt down to 3.3 (lower was broken)
and got the same behavior on each version of clang.
gcc seems to catch both on every version that supports c++11.</pre>
