Remove excessive constant declarations

When all .cc files are #included from a single master C++ file,
repetitive constant definitions - although the constant value remains
the same - makes MSVC error out.

Besides, it is not a good practice to redefine same constant over and
over again. It defies the main idea of constants: "define once, use
many times".
