-fsemantic-interposition was added in GCC 5.1. I don't think lots of projects in the wild are using it. The important D20217 <https://reviews.llvm.org/D20217> has been merged, I think we should actually implement this option instead of ignoring it (I'd be very happy to help this).

Can you just name the user groups? :) When they write `-fsemantic-interposition`, do they know that current clang doesn't match the GCC behavior?
