1  /* Regression test for bug in convoluted situation involving token paste
       2     plus function-like macros used outside function context.  It may be
       3     easier to understand if you mentally replace 'struct' with 'A'
       4     throughout this file; 'struct' is used only to get the code to compile
       5     when preprocessed correctly.
       6  
       7     The original problem was seen in the Linux kernel and reported by
       8     Jakub Jelinek <jakub@redhat.com>; this test is synthetic.  */
