The ASAD rewrite includes a (slightly modified) copy of SGI STL, currently 
at release 3.1.  Our goal is to have it identical, but that will depend 
on (even more!) cooperation from Matt Austern at SGI.

Things left to do include putting "feature-select" macro guards around
the non-standard extensions and renaming some types and templates that
have "__" in their names.  (These can interfere with name-mangling on 
some targets.)  Most of the other differences are in how things are 
split up into files and how the files are found -- these make a difference
particularly when you want to keep track of (or avoid) the use of 
extensions, or when you are ready to support separate template compilation.

There will be very good reasons to want to support separate template
compilation.
