> A recursive mutex using pthread_mutex_init() works.

Thanks for the analysis.

I'm going to add some extra preprocessor conditions around the __mutex_base and
__recursive_mutex_base initialization so that target maintainers can force use
of the pthread_mutex_init function on an OS-by-OS basis.  That should allow
this issue to be fixed for Lion and PR 51296 to be fixed for Tru64.
