 Be carefull with this test : it was designed for the *current* regexp
 engine, this means, for example, that these tests must be modified for
 Onigurama. Because Oniguruma will give different results.

 No need for this : just write an C extension which do this, and use this
 extension *only* for testing your regexp engine.

 Nobody, except you, need to modify these variables.
