This build problem first occurred a couple years ago for me, and I just noticed the latest code I pulled from github still has the same issue. Steps to...
In my opinion this isn't the responsibility of io, nor any other library to do. It's not third party developers fault that GNU ld is "dumb" (I don't use that...
