Subject: [PATCH] make siglongjmp void

In current setjmp.h, we have:
int	siglongjmp(sigjmp_buf env, int val) __attribute__((__noreturn__));

However, being a noreturn function, it should be a void one
(cf. the glibc man page.)  And the assembly code directly forwards
it to longjmp() which is void, too.   I suggest changing it:
