--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-06-18 15:26:03 UTC --- We know the instantiations that are needed, but I don't want to define them for all platforms if they're not needed elsewhere. I also have no way of testing on AIX, so someone needs to run the teststuite with the changes.
