+1.

I'm just testing a change (and some new icu libs for x86 only) to add an
option to build with libstdc++6 - that is, "-Duse.libstdc++6=true".

What should the default be?  Currently all the linux platform libs that
are checked in depend on libstdc++.so.5 but I'd be surprised if this
was still the most common version?  (Of course, the fact that all the
platforms have been "independently" compiled and ended up like using
libstdc++.so.5 would imply that I'm wrong.)

Agreed.  This would make the install considerably more error prone and 
time consuming. ;-)

-Mark.
