Part of the C11 threads implementation process should be adding threads.h 
to the conform/ test coverage.  That means conform/data/threads.h-data 
matching C11 requirements; adding threads.h to conformtest-headers-ISO11 
in conform/Makefile; ensuring that linknamespace-libs-ISO11 includes any 
libraries required for the C11 threads functions.  Then, make sure the 
tests for ISO11 all pass; any linknamespace failures for threads.h 
indicate cases where you need to call __* names with the public names 
being weak aliases.  That will help you catch any non-obvious cases where 
the call to a non-C11 function might be at several levels of indirection 
from the C11 threads implementation.
