  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.
