--- Comment #9 from Scott Lipcon <slipcon at gmail dot com> ---
We saw the same issue with gcc 4.9.2 on x86_64 Linux - we build the compiler
with --disable-shared in order to be able to deliver our software on systems
without libstdc++.so. Without the patches in this issue, we were unable to
link our .sos to libstdc++.a because of the missing -fPIC. The patch I ended
up using was a bit different than those in the comments below, but seems to be
working for our installation:

I hope this gets applied to an official release at some point.
