ARB_point_sprite & NV_point_sprite on Catalyst 3.9

In supported extensions string there’re ARB_point_sprite and NV_point_sprite. But i’ve got null pointer to glPointParameteriNV(), and a call to glPointParameterfvARB(GL_POINT_DISTANCE_ATTENUATION_ARB, @Coeffs) doesn’t affect in an appropriate way. Does anybody run into this already?


glew tells such thing about extension:

GL_NV_point_sprite: MISSING [OK]

glPointParameteriNV: MISSING
glPointParameterivNV: MISSING
