Re: [PATCH v2 1/2] libstdc++: Implement more maintainable header

[David Edelsohn via Gcc-patches]

Hi, Arsen

This patch broke bootstrap because it has introduced a new GCC build
requirement for autogen that is not a previous requirement to build GCC.
Previously the repository has included post-processed files.

+# AutoGen <bits/version.h>.
+.PHONY: update-version
+update-version:
+       cd ${bits_srcdir} && \
+       autogen version.def
+


Thanks, David
