Do you think we could add -Wcast-qual as a default flag to the libstdc++
testsuite?  I cannot see any downside (apart from the extremely unlikely
case that GCC contains a bug that only triggers when -Wcast-qual is not

In the meantime, and assuming Gawain will work on fixing the remaining
issues, how about the small patch I proposed at


which at least fixes one of the issues and will, in some form, be needed
also for a complete fix.  (Patch included also below.)
