1  /* Various integration tests for setjmp-handling expect a precise
       2     multiline output.
       3     
       4     The outputs from -fdiagnostics-path-format=inline-events for such
       5     setjmp tests are dependent on whether setjmp is a macro or a function
       6     (and whether that macro is defined in a system header).
       7  
       8     setjmp is a function on some systems and a macro on others.
       9     This header provides a SETJMP macro in a (fake) system header,
      10     along with precanned decls of setjmp, for consistency of output across
      11     different systems.  */
