Of course it is going to take gcc3 longer to compile things with the new
profiling code (see http://gcc.gnu.org/news/profiledriven.html)
All this basically is is the compiler running through code branches and
identifying blocks which should be optimized to produce faster
EXECUTABLES, this does not come at the price of faster COMPILE TIMES, as
the compiler has to build these profiles to do more advanced
optimizations. So, you are really benchmarking the wrong thing here.
