Hmm... Why did you add me as a reporter?

Much better, thank you! Please add the links to GCC's docs, like in
most attributes (some newer attributes may have been added without
them -- I will fix that).

In any case, no need to send a new version just for this for the
moment, I would recommend waiting until others comment on whether they
want `__optimize__` used here as the workaround.

Cheers,
Miguel
