If there is no alternative, make function unavailable on Windows 64 bit instead
of using a 0 assertion.

real nearbyint(real x) @trusted nothrow @nogc
{
    version (CRuntime_Microsoft)
    {
        assert(0);      // not implemented in C library
    }
    else
        return core.stdc.math.nearbyintl(x);
}
