State-Changed-Why:
    I'm not an expert, but Comeau compiles this too, and if G++
    and Comeau compile it, I tend to believe it's correct 8-)
    
    I suspect the unary plus decays the string literal to a
    pointer to const char, which then combines without problems
    with the binary '+' of std::string after a conversion of
    const char * to std::string.  But I could be wrong 8-)

    I've verified that indeed, Neil's analysis is correct.
    
    Not a bug.
