This seems related to bug 40855. See also
<http://gcc.gnu.org/ml/gcc-patches/2009-11/msg00652.html> and the rest of
that thread. libstdc++ support for extended integer and floating-point
types covers more than typeinfo; see what I said at
<http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01912.html> and the
followups thereto. There's numeric_limits (see bug 40856), and I/O
support (with the same issues as for libgfortran about avoiding
libquadmath in static links if the functionality isn't used in a
particular program), and mathematical functions, and maybe more -
certainly most of that would not be suitable for 4.6, however.
