ya missed the point.... index is being used as a variable in the code
and is a function in the strings.h package. kinda like when someone
declares the variable number, but there is a number func in the circle
code.

-Wshadow catches when a local variable shadows another local variable.
I don't see the relation between two functionally equivalent functions
(heh, relation and function...get it? Bah, math puns) and the
-Wshadow parameter. BTW, just because two functions take the same
parameters and give the same result, doesn't mean they do it in the
same way.
long my_pow_2(int p)
{
return (2 << (p-1));
}
long math_pow_2(int p)
{
return ((long)pow(2, p));
}
They'll both return the same result, and they both take the same
argument, but I can be fairly certain that my_pow_2() is faster,
if only because it doesn't do a cast and a second function call.
