It looks like you are linking against the libstdc++.a from an older
(modified by mingw local patches) version of gcc.
The symbol __w32_sharedptr_unexpected does not occur in FSF  sources for
3.4.0.

I suspect that if you change PATH so that the relocatability magic finds
the new (3.4.0) gcc driver before it finds your old one you will link
against the correct 3.4.0 libstdc++.a.  In your example, simply, putting
'.' at the start of your path (since you are running g++ from the 3.4.0
bin directory) should do it.

Or, you could build with --enable-win32-registry and edit the registry
rather than changing PATH.
