I'm guessing Cygwin does not support the functionality declared in the
headers yet.
I think the explanation is simpler. The problem is that the
shared_mutex header uses some pthread_rwlock_* functions (if __cplusplus
>= 201402L) but the declaration of these in pthread.h is guarded by
#if __XSI_VISIBLE >= 500 || __POSIX_VISIBLE >= 200112
I've submitted a patch to fix this:
