Can you provide a stand-alone test program that demonstrates this?

I tried it myself and I got the expected result: mod(4.0, 2.0) returns 0.0

Mesa's mod() function is implemented just as the spec says:

float mod(const float a, const float b)
{
    float oneOverB;
    __asm float_rcp oneOverB, b;
    __retVal = a - b * floor(a * oneOverB);
}
