- Whose bright idea was it to add unrelated functionality to just about
- the only function in the standard C library (setjmp) which cannot be
- wrapped by an ordinary function wrapper? Anyway, the damage is done,
- and therefore, this wrapper *must* be inline. However, gcc will
- complain if this is an inline function for unknown reason, and
- therefore sigsetjmp() needs to be a macro.
