Clearly the proper wrappers to provide would be C1x <stdatomic.h> rather 
than exporting glibc's internal interfaces.  Given the tricky ABI issues 
and compiler interaction, I think you want to wait for the compiler work 
described at <http://gcc.gnu.org/wiki/Atomic> to be more nearly complete 
before implementing the header in conjunction with the people working on 
that compiler support.
