I think standard of C std libs declares setjmp as a function. So, it should be
function.

Some code:

__BEGIN_NAMESPACE_STD
typedef struct __jmp_buf_tag jmp_buf[1];

extern int setjmp (jmp_buf __env) __THROW;

__END_NAMESPACE_STD

#ifndef    __FAVOR_BSD
extern int _setjmp (struct __jmp_buf_tag __env[1]) __THROW;
# define setjmp(env)    _setjmp (env)
#else
# define setjmp(env)    setjmp (env)
#endif 

Do you see that if __FAVOR_BSD is defined then std::setjmp will work? Different
behaviours aren't good.
