If rumors and memory serve me well, here, MS VC++ is supposed to do
exactly that, already. The feature is usually called "incremental
compilation" by the marketeers, as it's meant to only recompile stuff
that really has changed, or was affected by changes elsewhere in the

But using this on templates like in the C++ STL is an altogether
different game, as a template is not self-contained. It'll have to be
recompiled again each time you use it with a different parameter type,
which (assuming template recompilation issues have been handled
earlier), would mean every single time you compile it at all.
