In general, it would be nice to move all compiler attributes to use
the `__` syntax, which is independent of compiler vendor, gives us a
level of indirection to modify behavior between compilers and is
shorter/nicer for users.

But it is low priority, so it should go in whenever it causes the
least amount of trouble.
