Well, I have my own test suite populated by bugs I've discovered over the
last year.  It has over 250 entries in it.  I run it once in a while, to make
sure old bugs haven't made their way into the code, and sometimes they do.

 If any1 has been doing the same, we could merge it, and have
something similar to GNU's testsuite.  Of course,  make dobench still
needs the existing short testsuite for the purpose of deriving
benches.
