* const int (*cptr)[10] = ptr;
*
* is not allowed and most compilers will generate noisy warnings about

* Clang will allow it if you make the array type a typedef, like this:
*
* typedef int int10[10];
* int10 *ptr;
* const int10 *cptr = ptr;
*
* however GCC does not and still issues the incompatible type warning. The
* "proper" way to fix it is to add an explicit cast for the constified type,
* but that removes the vast majority of otherwise useful type-checking you'd
* get, and runs the risk of improper casts if types are later changed. Leaving
* it non-const can also be an issue if you use it as a function parameter, and
* happen to have a const type as input (and also reduce the capabilities of
* the compiler to better optimize the function).
*
* So to work around the problem, we use a macro. The macro first assigns the
* incoming variable to the specified non-const type to ensure it's the correct
* type, then casts the variable as the desired constified type. Very ugly, but
* I'd rather not have hundreds of lines of warnings because I want to tell the
* compiler that some array(s) can't be changed by the code, or have lots of
