Building dejagnu with latest GCC

[Richard Kenner]

    Kenner, please could try to replace

        sb->setbuf(bbuuff, 5120);

    with

        sb->pubsetbuf(bbuuff, 5120);

    and report what happens?

That does it.  Thanks.

There really should be some web page capturing all this and giving
the versions of tools that are needed.
