Strange warnings from GCC++ 4.6.2 in Atmel Studio 6

["George H. Barbehenn" <gbarbehenn@xxxxxxxxxx>]

GCC:
    I get the warning:

Warning    1    deprecated conversion from string constant to 'char*' 
[-Wwrite-strings]

    It is thrown on the following line:

myGLCD.print("* Universal Color TFT Display Library *", CENTER, 1);

    There are two overloads of the print method:

        void print(char *st, int x, int y, int deg=0);
        void print(String st, int x, int y, int deg=0);

    (folded code):
void UTFT::print(char *st, int x, int y, int deg)
{
}

void UTFT::print(String st, int x, int y, int deg)
{
}

I'm not sure why the compiler is confusing the overloads, is "String st" 
somehow equivalent to "char *st"?
