// pthread.h and setjmp.h cannot agree on the type of __sigsetjmp:
//
//   extern int __sigsetjmp (struct __jmp_buf_tag *__env, int __savemask) __attribute__ ((__nothrow__));
//   extern int __sigsetjmp (struct __jmp_buf_tag __env[1], int __savemask) __attribute__ ((__nothrow__));
//
// With -Wall, gcc-11 warns about the disagreement unless the CPP directive
//
//    # 1 "/usr/include/pthread.h" 1 3 4
//
// appears, which appears to be witchcraft. Unfortunately, this directive is removed by the CFA preprocessor, so the
// batchtest fails because of the spurious warning message. Hence, the warning is elided.
