String literals

Hi,

I have a problem in understanding what is wrong with the function call
'fun1(pc1)' in the code below. I am sure I am missing something really
basic and silly in my understanding.

void fun1(const char (& arr)[5])
{
	cout << sizeof(arr);
}
int main(int argc, char **argv){
	const char *pc1 = "2008";
	const char pc2[] = "2008";
	fun1(pc1);
	fun1(pc2);
}

All of VS2008, g++ and Comeau give error in the compilation stating
that it is not possible to convert 'const char *' to 'const char (&)
[5]'

2.13.4/1 states the following "An ordinary string literal has type
``array of n const char'' and static storage duration (basic.stc),
where n is the size of the string as defined below, and is initialized
with the given characters.".

With this understanding I think that fun1(pc1) call should also be
successful as is fun1(pc2)
