If you statically link expat, and have a reasonable smart compiler, it
should check in at less than 100kb (we get it down to about 75kb even with
UTF-16 and namespace enabled).  Creating a dynamic library (e.g. DLL or
so) tends to be larger because the compiler isn't sure what code will and
won't be called.  If you need a dynamic library (maybe because multiple
programs use the library) then you should be able to trim some code from
unused areas by tweaking your compiler and linker settings.
