STL is not configured in the usual sense when you build EGCS (I don't
remember what FSF gcc does anymore, but it's moot since the C++ front
end FSF gcc is too buggy to be usable in any case), but simply added
on as 3rd party code without any changes.

A simple patch like the following to STL folks stl AT sgi DOT com should fix 
this. SGI STL team is very responsive. This is completely untested
of course, so usual caveats apply.
