<pre>For example:
$ cat | bin/clang-cl /c /Tp -
namespace { struct T { }; }
struct __declspec(dllexport) S {
void foo(T &t);
};
void S::foo(T &t) { };
<stdin>(7,9) : error: 'S::foo' must have external linkage when declared
'dllexport'
void S::foo(T &t) { };
^
1 error generated.
Since T is in an anonymous namespace, S::foo gets internal linkage, and Clang
errors when trying to dllexport it.</pre>
