Comment (by rmottola):

 today I am upgrading 10.11 and - without further patches - it fails. Same
 error with clang11:


 {{{
 crypto/threads_pthread.c:214:1: error: redefinition of
 'fallback_atomic_exchange_n_uint64_t'
 IMPL_fallback_atomic_exchange_n(uint64_t)
 ^
 crypto/threads_pthread.c:186:26: note: expanded from macro
 'IMPL_fallback_atomic_exchange_n'
     static ossl_inline t fallback_atomic_exchange_n_##t(t *p, t v)
 }}}



 I do wonder, it is 64bit and it did upgrade on 10.5 64bit and 10.7 64bit!
 So I am a bit puzzled, wonder if it depends on some "context" of compiler,
 legacy-support or something else? @jmroot
