 *	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).
 *
 *	Restore _all_ the registers and the signal mask atomically.  Can
 *	use sigreturn() if sigreturn() works.
