That name is in the user's namespace, so it should not be tested in any 
installed header.

If you're not changing the API/ABI, I don't think the patches belong in 
glibc master (as opposed to on some branch, and on the branch you can just 
enable the features by default).  This isn't a case where a long series of 
preparatory patches are needed before adding a feature (which is the sort 
of case where preparation for a new feature might be appropriate on master 
long before the feature itself); the main preparation for the feature was 
all done in the x86_64 context.
