Bootstrap of current trunk on powerpc64-linux fails in libstdc++ building system_error.lo. The code that fails was added a few days ago, but the failure seems to be the same as the one reported in PR 31490. I verified that the patch from comment #10 of that PR allows bootstrap of c,c++,fortran to succeed and now I'm doing a bootstrap and regtest of all languages but Ada. I'll report the results in the PR.
