I haven't looked at STLPort's implemenetation of this. However, this will make
the problem of too much preprocessed source worse, not better, as it will
involve more code, although the eventual executable might be smaller.

I did implement a version of this myself, basically by writing a mapper around
each container that did a few static_casts and mapped the functions to a void*
version of the container. However, having a whole new bunch of inline functions
causes problems for the compiler, without providing (as far as I could measure)
significant reductions in the size of the executable.
