State-Changed-Why:
    Yep, just like mandated by the C++ Standard.  String literals may be implicitly converted to type char*, but since operands 2 and 3 of the ternary operator have type const char[], they decay to const char *, and then, the result of the ternary operator cannot be converted to char*.

>Description:
When compiling the attached file with "g++ -c const.cpp",
the compiler emits for line 6 (with the ternary operator)
but not for line 5.  Somehow, when a string literal is
evaluated by the ternary operator, the type comes out as
"const char *", but otherwise, they are silently converted
to "char *".
>How-To-Repeat:
Compile the attached file with any options you want.
>Fix:
Rewrite the ternary operator with an if-statement and a
temporary variable of type "char *".
