In no way at all. The `const' qualifier is only a hint to the
compiler that the qualified object is not intented to be ever
modified, so it can emit warnings for possible modification attempts.
In C++, you can actually declare a constant with it, but in C, you can
only declare a variable that is not supposed to be modified.
