How to cast pointer value to enumeration?

I have the following:

enum TestEnum { One=1, Two, Three };

int main()
{
    char const* data = reinterpret_cast<char const*>(One);

    TestEnum e = reinterpret_cast<TestEnum>(data);
}

Clang fails to compile this:

main.cpp:11:18: error: reinterpret_cast from 'const char *' to 'TestEnum' is not allowed
    TestEnum e = reinterpret_cast<TestEnum>(data);
                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

Why won't reinterpret_cast work in this situation? I've tried removing const but that doesn't make a difference. I didn't see anything in the C++11 specification that states special behavior for enumerations.
