Theres the C version:
float VectorNormalize (vec3_t v){
float length, ilength;
length = v[0]*v[0] + v[1]*v[1] + v[2]*v[2];
length = sqrt (length); // FIXME
if (length) {
ilength = 1/length;
v[0] *= ilength;
v[1] *= ilength;
v[2] *= ilength;
}
return length;
}

Thats why return a float. Because is C code. And is the right thing
for "Think in C" mode. But is the wrong thing for "Think in OOP" mode.
So is right that Valve change this stuff.
