Actually, on further thought I realize that we shouldn't be advertising WGL_EXT_swap_control unconditionally.  It should be controlled by the AllowVerticalSync registry setting / allow_vsync variable.  See load_extensions().  If vsync is disallowed, the corresponding functions are left as NULL in the OpenGL function table, so clients may crash if WGL_EXT_swap_control is advertised.
