        <pre>As reported to me via MacPorts trac, recent trunk fails to include a static
implementation of operator delete(void*, unsigned long) and thus fails to link
when using --std=c++14

$ cat foo.cc
int main()
{
  auto f = new int;
  delete f;
}
$ clang++-mp-3.6 -std=c++14 foo.cc
$ clang++-mp-3.7 -std=c++14 foo.cc
Undefined symbols for architecture x86_64:
  "operator delete(void*, unsigned long)", referenced from:
      _main in foo-7bc325.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)</pre>
