In lieu of a real regression, these tests are based mostly on bugs
present in previous versions (thanks to all that mailed in the
reports!)

The shell script works only in unix, and just compiles each test
and compares the output with the expected output.

Running "sh runtest.sh" ought to do the trick.

Note that running test3 creates a very large scanner, so
you'll need to be patient while the beast chugs away.
