No symbol exported by libstdc++ includes the mangling of va_list. This
affects the C++ ABI for objects exporting interfaces involving va_list,
but libstdc++ is not such an object.
This does however need a release note for gcc-4.4/changes.html noting the
ABI change (see the GCC 3.4 release notes for previous such notes for
several targets).
