/* Test __attribute__((gnu_inline)).

   Check that __attribute__((gnu_inline)) has no effect, in the
   absence of extern and/or inline.

   Check that we don't get out-of-line definitions for extern inline
   gnu_inline functions, regardless of declarations or definitions.

   Check that such functions can be overridden by out-of-line
   definitions.
