45 * Rename sigsetjmp to __sigsetjmp and siglongjmp to __siglongjmp,
46 * remove the other *jmp functions and define everything in terms
47 * of the renamed functions. This requires compiler support for
48 * the renamed functions (introduced in gcc-2.5.3; previous versions
49 * only supported *jmp with 0 or 1 leading underscores).
51 * Restore _all_ the registers and the signal mask atomically. Can
52 * use sigreturn() if sigreturn() works.
