I can re-send them later on, no problem. On the other hand, doing the
changes will push tools to get updated sooner ;-)

If tools were doing something as fancy as comment parsing for
diagnostics, they should have been updated with the attribute support
(either gcc's or C++17's) -- it has been more than a year now since
gcc 7.1 and the C++17 final draft. (Note that this does not apply for
things like clang, since they weren't doing comment parsing to begin
with.)

Cheers,
Miguel
