- *	Rename sigsetjmp to __sigsetjmp and siglongjmp to __siglongjmp,
- *	remove the other *jmp functions and define everything in terms
- *	of the renamed functions.  This requires compiler support for
- *	the renamed functions (introduced in gcc-2.5.3; previous versions
- *	only supported *jmp with 0 or 1 leading underscores).
- *
- *	Use sigprocmask() instead of sigblock() and sigsetmask(), and
- *	check for and handle errors.
- *
- *	Restore _all_ the registers and the signal mask atomically.  Can
- *	use sigreturn() if sigreturn() works.
