You can use c++filt (part of binutils) to demangle the names, but
there's a catch.  The output of the typeid(x).name() string does not
match the format that c++filt expects (not sure why, but more info here
http://gcc.gnu.org/ml/gcc-patches/2002-01/msg02107.html )

You can prefix the mangled type name with a _Z to get the proper
demangled type name.

ex:

for
> St6vectorISsSaISsEE

c++filt _ZSt6vectorISsSaISsEE yields

std::vector<std::basic_string<char, std::char_traits<char>,
std::allocator<char> >, std::allocator<std::basic_string<char,
std::char_traits<char>, std::allocator<char> > > >

Notice the _Z prefix.

Hope this helps,
- Dave
