             Bug #: 50196
           Summary: std::thread can not use under macos.
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: watsonsong@foxmail.com


I try to use std::thread on MacOS X 10.6.8.
As the library is a new feather in c++0x, I use compile flag -std=c++0x, but it
can not find std::thread when I include thread header file.
I find the _GLIBCXX_HAS_GTHREADS is not defined, and that because
_POSIX_TIMEOUTS is not defined on MacOS and there is no implement of
pthread_mutex_timedlock.
Can libstdc++ is more portable, if boost::thread is avaiable on MacOS, I wish
the g++ can support it natively.
