  Does anyone already use bbv2 with profile guided optimisation (/PGO 
/PGI) ?

  The  build process is a bit special, since you first need to compile 
an instrumented executable. Then you run it on typical program input. 
This generates some profiling informations and then you only need to 
relink the executable providing this information with differents options.

  I don't know how to do this since this is not only a set of options to 
choose (new variants) ? The compiler i use is microsoft visual studio 8.

Thanks,
