Visibility attribute?

[Michael Thaler]

Hello,

I just saw that I get lots and lots of warnings when I compile Krita:

In file included from ../../core/kis_color.h:28,
                 from ../../core/kis_view.h:45,
                 from ../../core/kis_filter.h:29,
                 from kis_multi_integer_filter_widget.cc:27:
../../core/color_strategy/kis_strategy_colorspace.h:330: warning: `visibility'
   attribute does not apply to types

What does this mean?
