I don't know whether Andrew intends stdatomic.h to go in GCC or glibc, but 
in any case I consider this a duplicate of bug 53769, which in turn I 
don't really consider a useful bug report at all (incompleteness of the 
implementation of an option documented in the manual as incomplete should 
not be considered a bug).
