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?
