Yes. It's work in progress at the moment. We'll post a notice here |

when it becomes available. |

"Hardened GCC" is a Gentoo thing where we change the normal default |
| 19 |
settings of the compiler - it has nothing to do with upstream GCC so |

you won't see any mention of it on the GCC website. |

That is correct. However SSP is not switched on by default in the |
| 29 |
normal compiler (that is part of what the "Gentoo Hardened GCC" does). |
