It is not just ASIO, but many other libraries.

1. I do turned on full optimization (for size -Os),
2. 4.3 is quite latest and I don't have access to 4.5 (it is not even
released yet...)
3. The issue is not compiler but maybe linker itself.
What happens:
Each sample server I compiled implemented its own "select loop", wait
queue, even dispatcher, mutexes etc, etc.
Each module compiles independently, it does not know if there is another
module which implements same routines -- so there is lots of work for
linker to find shared routines and merge them. I'm even not sure that
according to standard it suppose to do such things.
