Forgot to add this to the initial inlining comment: for the required
types in iostreams, locales, etc. (ie, the ones that the library
 instantiates and thus the ones that matter for the library ABI) I used
 the 'extern template' trick to remove inline instantiations, so the
 situation is not quite as bleak as was made out previously.

If you look at a shared executables, you'll see that very little is
 in object files that doesn't need to be there: that's what "tune for
 size" was all about....

For the STL classes, I think the only thing that needs to be addressed
are the instantiations already in the library.

For the most part, those are in src/stl-inst.cc, right? 

(checks)

Oh right, there's almost nothing in this file now. So, what's stopping
this cleanup from happening again?

Perhaps I'm being dense, and all these French holidays are making me
 soft...

Sounds great.

Certainly looks like a vast improvement to me. Thanks for doing this,
since it seems to have bugged a large number of people for a long time.
