Hi John,

I'm having an issue with gcc-5.1 on MacOs.

BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE  is not defined.

I see that there are things like

#if __MACH__ && !defined(_MSL_USING_MSL_C)
...

#  if (__GNUC__ == 4)

// Both gcc and intel require these.
#    define BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE
#    define BOOST_HAS_NANOSLEEP

#  endif
#else
...
// BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE not defined here
#endif

Wondering why the GCC version must be 4 and why when _MSL_USING_MSL_C is 
defined these PTHREAD attributes are not defined neither.

BTW, when I compile with version 4 everything works correctly.

Vicente
