--- Comment #10 from Philipp <s...@s-e-f-i.de> 2012-02-15 12:02:09 UTC --- But think about a header only library. My test case isn't that far fetched. A simple struct with no member functions (except for the implicitly generated ones) should need no visibility at all, in my opinion. I can work around this somehow, but wouldn't it be better to fix it?
