I downloaded Code::Blocks a few days ago, and gotta say, good work guys

I installed the C::B Version which also brings a mingw compiler along, since
i only have an old MSVC 6...
So, now i startet playing around with some files, and also installed boost.
I was playing a little with boost::filesystem, but than wondered why my
executable was 2 MB big. So, i used the wrong library (debug).
With the normal boost::filesystem library the excutable is just 570 k,
which still is a bit big for a small programm, which only purpose it is
to test some code & compiling.
Then i created a Hello World Project, to see what a 'normal' Hello World
would compile to. Still 470 K.
I started then my old MSVC and copyied the project to it.
Result: Debug Version : 510 Kb, Release: 96Kb.
So, my question is, how can i make the Mingw make a smaller excutable
than now (if its gonna be better than 96 is not so important *g*), but smaller
than 470 would be quite good.
Can i do this by configuring the compiler options in C::B, or how could I achive that ?
