why my C++ output executable is so big?

Question

I have a rather simple C++ project, which uses boost::regex library. The output I\'m getting is 3.5Mb in size. As I understand I\'m statically linking all boost .CPP files,

If you are statically linking then most linkers will only include the objects that are needed.

3.5Mb is not that big - on a PC system so size could depend on OS etc
