             Bug #: 54847
           Summary: --enable-libstdcxx-time=yes non-functional on darwin
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: howarth@nitro.med.uc.edu


The configure option --enable-libstdcxx-time=yes is non-functional on darwin
because the associated configure test requires posix-timer support which darwin
lacks. Darwin also lacks support for the tested clock_gettime call but does
have the sched_yield call available. Also it is odd that
--enable-libstdcxx-timer has been defaulted to no as this has left many darwin
users (including MacPorts) assuming that they are enabling it with that option.
