** File:        lazyinit.c

** Description: Testing lazy initialization

**

**      Since you only get to initialize once, you have to rerun the test

**      for each test case. The test cases are numbered. If you want to

**      add more tests, take the next number and add it to the switch

**      statement.

**

**      This test is problematic on systems that don't support the notion

**      of console output. The workarounds to emulate that feature include

**      initializations themselves, which defeats the purpose here.
