At first, I applied the patch to my previous build tree and reran make and make check in libstdc++, but the failures persisted. To make sure there wasn't any missing dependency, I removed the libstdc++-v3 directory, reconfigure and rebuilt, but with the same results. I happened to build on Tru64 UNIX from the same sources, and see lots of wchar_t failures there, too. Rainer
