It would be really great if this patch got installed on the 3.0 branch
to prevent the above problem and enable better testing of g++.  It was
installed on the main over a month ago.  I believe a number of others
have asked for it.

I tried upgrading to the latest cvs version and using it with the branch
but ran into this problem under hpux:

...
checking for threads package to use... threads-no.h
checking for exception model to use... configure: error: unable to detect except
ion model
make[1]: *** [configure-target-libstdc++-v3] Error 1

DCE threads are available on the system but the gcc option `-threads'
must be used to detect/build/link with this thread package.
