5491 Some of these reference functions in the perl object files, and some

5493 functions, so including this file in source code can cause link errors
5494 even if the source code uses none of the functions. Hence including these

5496 (obviously) result in unworkable XS code, but allows simple probing code
5497 to continue to work, because it permits tests to include the perl headers
5498 for definitions without creating a link dependency on the perl library
