Not a big deal IMHO, but the below simple check works well for me on
x86_64-linux.
Just fyi, gcc accepts
decltype(main) x;
decltype(sizeof(decltype(main)*)) x;
which are "uses" of main and also violate [basic.start.main]/3.
"good" to know. In my experience sometimes the front end appears to
so-to-speak pre-declare entities. For instance I filed a while ago
c++/48396. Not sure if in practice the exact same code is involved...
