This patch already does what you are asking for (remove the extra
const), isn't it ?

I looked at my textbook (The C programming Language, By Brian W.
Kernighan and Dennis M. Ritchie.) and it says:

The const declaration can also be used with array arguments, to
indicate that the function does not change that array:

int strlen(const char[]);

and so this patch isn't necessary for sure.
