12617	clock_gettime not available on OS X 10.11	djh	Ion Gaztañaga	"Looks like the Boost.Interprocess check for `clock_gettime` does not correctly handle OS X 10.11.

(see os_thread_functions.hpp)

Here is a small self-contained test case triggering on OS X 10.11 with xcode8:

{{{
$ xcodebuild -version
Xcode 8.1
Build version 8B62
}}}


{{{
#include <iostream>
#include <boost/interprocess/detail/os_thread_functions.hpp>

int main() {
    boost::interprocess::ipcdetail::get_current_system_highres_count();
    std::clog << ""hello"" << ""\n"";
    return 0;
}
}}}

{{{
$ clang++ -o t t.cpp -Imason_packages/headers/boost/1.61.0/include/ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk -Wl,-bind_at_load

$ ./t

Seems like is does not trigger on OS X 10.12, though."	Bugs	closed	To Be Determined	interprocess	Boost 1.61.0	Problem	fixed
