My code is not built with inlining disabled.  For compiling I use '-mp 
-pc64 -DBOOST_ENABLE_ASSERT_HANDLER' with the addition of '-O2 -xN 
-vec_report0 -DBOOST_DISABLE_ASSERTS' for optimized and '-g' for debug 
versions.  For linking I use '-Wl,--export-dynamic'.

I will try this.

We tried 8.1, but it produces code that is slower than g++ 3.4.4 for our 
application, so we are retiring the Intel version.  It also has a bug 
that Intel only fixed in 9.0.
