In general, "regression" refers to a program failing
on test cases that it used to succeed on. "Self-test"
refers to a program that tests itself somehow.
euphoria\demo\sanity.ex is a good example of a program
that tests for regression by using lots of little
"self-tests" to check for failures.

When I run build.bat on Windows, the translator is
used to build a new interpreter and new translator.
The interpreter is built using the translator with
Watcom, while the translator itself is built using
the translator with Borland. So if I accidentally 
introduce a Borland-specific regression error in the translator,
I will probably notice it very soon because I will have
broken the ecw.exe translator executable itself.
I probably won't have to wait for a Borland user to 
report the regression bug.

(This incestuous build process is a bit hard to
fathom sometimes!)
