What do the others use? IIRC Homebrew enables that construct but the system
linker ignores it completely; this means instead of a compile failure you
may get runtime failures. (And if you don't get runtime failures then
perhaps these attributes were not needed in the first place.) The system
linker is the issue here; while MacPorts can build its own copy of that
(often with bugfixes from later OS X releases), as yet nobody has
implemented the feature in question in OS X ld at all.
