--- Comment #1 from David Majnemer <david.majnemer at gmail.com> ---
Clang is aware, it just won't tell you unless you pass -pedantic:
<stdin>:5:7: warning: ISO C forbids taking the address of an expression of type
'void'
      &foo; // 2
      ^~~~
<stdin>:5:7: warning: expression result unused
      &foo; // 2
