>Description:
In C++, a string literal is of type const char[N].  However, there is a special conversion, just for string literals, that lets you assign a string literal to char*.

This conversion is known to be unsafe, it was put in to support legacy code that isn't const-correct, and it is deprecated.  The compiler should issue a warning when it applies that conversion.  The only issue is whether that warning should be on or off by default.
