--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Eric Gallager from comment #2) > I would prefer this second approach. The downside of it is that it requires adding a keyword that the standard says is completely redundant, in order to get compiler-specific behaviour. It's not clear why it's there, or if it's OK to remove it. A compiler-specific attribute obviously has compiler-specific effects.
