See https://bugs.gentoo.org/show_bug.cgi?id=498640: What compiler versions are supported for 3.3?

Do you mean gcc-4.2? The patch uses __GNUC_MINOR__ < 3. On the FreeBSD build slave gcc-4.2 works: gcc (GCC) 4.2.1 20070831 patched [FreeBSD] Are you sure that there aren't any gcc patches for this version? It looks like a gcc/binutils issue to me. |

This is the gcc bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46861 I rather agree with this comment: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46861#c3 If a distro still maintains 4.2.x, the toolchain should be fixed (like FreeBSD apparently did). |

OK, thanks for the quick response. Relaxing to normal priority, please close as required. |

Given this, WONTFIXing this seems reasonable to me, FWIW. |
