Thanks, I didn't know there was a DR for this. I find the standards text is a little vague but your change seems to indicate that cv-qualifiers never weighs into covariance. The reason I ask is we handle this explicitly in IWYU, and we treat cv-qual differences as covariant (requiring the complete type). It doesn't look like that was the standard's intent. We should probably follow Clang here in a coming release, assuming other compilers agree. It looks from the bug-report that they do, at least newer versions.
