  • Status changed from new to closed
  • Resolution set to wontfix

I don't think there's anything we can do to fix this: the warning comes from assigning PTHREAD_MUTEX_INITIALIZER to a pthread_mutex_t. So since the constant that generates the warning is defined in pthread.h I don't see what we can do :-(

If you can figure out a patch that would fix this then please do reopen.
