It's the version of gcc they're using with intel linux. The test passes  
for gcc-3.3, fails for gcc-3.4, gcc-4.0 and gcc-4.1. So the names could be  
changed to something like intel-linux-9.0-gcc-3.3 and  
intel-linux-9.0-gcc-3.4. You can see the version details in

I tried adding some output to the test:

int test_main( int, char*[] )
{
     int counter = 0;

     BOOST_FOREACH(int i, get_vector())
     {
         std::cout<<i<<"\n";
         counter += i;
     }

     std::cout<<"Total: "<<counter<<"\n";
     BOOST_CHECK(16 == counter);

     return 0;
}

And got the following:
