I want to define some global constant vectors like:

const XMVECTORF32 RED = {1.0f, 0.0f, 0.0f, 1.0f};

The above works and does not give me errors, but I am wondering why the xnamath.h defines their globals like this:

#define XMGLOBALCONST extern CONST __declspec(selectany)

XMGLOBALCONST XMVECTORF32 g_XMSinCoefficients0 = {1.0f, -0.166666667f, 8.333333333e-3f, -1.984126984e-4f};

What is the difference? What does __declspec(selectany) do?
