--- Comment #2 from Benjamin Kosnik <bkoz at gcc dot gnu.org> 2011-09-23 03:47:55 UTC --- Created attachment 25346 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25346 patch You are correct Here's a patch that fixes it. The real issue is that now, linking libstdc++ is required for stage 1. To solve the issue of libstdc++ with versioned namespaces being built with this requirement mandates versioned namespaces changing the SO version to 7. This patch does this. However, it is not configurable. Instead, it is hard-wired. I plan on fixing this in a subsequent patch. This will mean configuring with --enable-symvers=gnu-namespace triggers libstdc++.so == 7. Thoughts, suggestions, or comments on this approach? -benjamin
