It does. You'll see that the jmp_buf is defined already and so we
don't redefine it. The problem is when we fall into the last part
which is enabled for CYGWIN and __rtems__ that needs the _JBLEN macro
to be set.
It looks like _JBLEN of 9 is what that structure is

Do you mean 9 ints or do you mean 36 ints? Because _JBTYPE is undefined,
it will declare _JBLEN ints.
