It had hit me when building LibreOffice against libstdc++ 13 trunk, so I started writing this hack.  In parallel, libstdc++ 13 trunk got changed again to not use `__is_unsigned` as an identifier, so there should be no published releases of libstdc++ where this would be an issue.  (And I had finished writing this hack anyway, just in case it might be useful.  And then forgot about it...  But maybe its best to just abandon it now.)
