<pre>Consider the following C++ code:
void global() {}
namespace { void anonymous() {} }
namespace detail { void detail() {} }
namespace detail { namespace { void detail_anonymous() {} } }
namespace { namespace detail { void anonymous_detail() {} } }
The functions global() and detail() should result in -Wmissing-prototypes
warnings. Clang 3.7 to trunk correctly warn on those, but also incorrectly warn
on anonymous_detail(). Clang does correctly optimize out anonymous_detail()
when it's unused.
GCC 4.9 to 6.3 (with '-Wmissing-declarations') correctly warns only on global()
and detail().</pre>
