--- Comment #2 from joseph at codesourcery dot com <joseph at codesourcery dot com> 2011-02-24 15:23:33 UTC --- 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.
