Is DejaGNU's testsuite useful? I admit, a strange question to have to
ask about a testsuite for a test harness package, but the results have
been pretty horrid every time I've tried it. I've attached some
patches that I used in Debian to allow make check to pass. But in the
end I had to turn the testsuite off again; it doesn't work when run
without an attached TTY.
