| Suppose you want to pass the address of a jmp_buf bar to a function foo. |
| Since jmp_buf is normally defined (typedef'd) as an array, you would do |
| it like this: foo(bar), where foo = foo(jmp_buf bar). But suppose a |
| jmp_buf is (say) a struct rather than an array. Then you must do |
| foo(&bar) where foo is foo(jmp_buf * bar). This is controlled here in |
| the traditional fashion, by ifdefs. By default, we assume that jmp_buf |
| is an array. Define the symbol JBNOTARRAY if jmp_buf is not an array. |
