51 * Note that while lib_setjmp() and lib_longjmp() behave like setjmp()
52 * and longjmp() normally do, gcc 3.1.x (and later) assumes things about
53 * how setjmp() and longjmp() should work (even with -fno-builtins).  We
54 * don't want it to do those, so these functions must be named differently.
