There are other reasons for not using someone else's string. I don't like
using SGI STL's string because it makes "-g" binaries about 5 times
larger than every other STL's string does. It also requires up to 180MB
to compile some of our files when exceptions are enabled (and since xtl
requires exceptions...you can guess the rest)
