Wrong list!

You can disable the warning by editing boost/config/compiler/gcc.hpp, line 62.
I don't think anything else needs to be done, but I am not entirely sure.

Try the attached trivial patch to avoid the ICE. This one patch is sufficient
to enable compilation of all our code (quite a bit). Some regression tests fail
with seg faults, presumably because the gcc 3.3 optimizer is buggy.

Post your problem reports and patches to boost_at_lists.boost.org.
