Attached patch to debian libstdc++ package is supposed to fix clang
compilation.I'm still waiting compilation to complete before I can
test it. The compilation will take long time in an armel vm. I decided
to share it in case someone else has faster test environment than I
The patch has extra src directory that needs to be striped with
s/\([ab]\)\/src/\1/g if someone tries to apply it to upstream sources.
