There's little effort to keep the GCC build warning clean, but I've
seen people cleaning up this particular warning, so feel free to
commit a fix for it (replacing the c-style cast with a const_cast if
it's intended, or just adding "const" to the cast if it wasn't
intended/necessary to remove const).

We should probably setup a GCC -Werror build bot if we are warning
clean for some sufficiently modern version of GCC.
