David, which version does/will include these recent additions?

I recently encountered a crash on program exit in AIX 6.1, in a setup where I
used a static C++ objects inside functions within a shared library (accessed
via dlfcn interfaces & closed via dlclose), compiled with a gcc-4.6.3.
Having the gcc configure flag "--enable-__cxa_atexit" in place and working
(meaning cxa_atexit is present) shall fix this issue.
