Description
When compiled with HP aCC 6.10 on HP-UX 11.23/IPF and stdcxx 4.2.1 the Stepanov and Stroustup's Standard Container Benchmark runs with the following output.

When compiled with the same compiler but the native C++ Standard Library the same benchmarks runs with the output below. Note that in most cases the times in this table are better than in the one above.
