I have started using boost and stl more which is why the code base has
shrunk but the binary has not grown that much you have to understand stl is
mostly templates and compilers do a pretty good job now days if you are
already using a list for example you don't get a whole other code segment of
list if you use two. You pretty much should only get a data section if the
compiler is working right.

How much do you make use of the stl? I use it everywhere. From holding
options to holding lists of players, rooms, zones, sockets, etc. I could
use libraries (and may at some point, possibly for some other stuff),
but only if I really need to worry about code size. Right now I was just
getting kind of worried that the use of the stl is going to cause
headaches and problems at some point sooner or later.
