Updating from ancient to old! Yes, GPLv3 and the way FreeBSD is handling it are unfortunate. In any case, lang/gcc45 and other FreeBSD ports I maintain use binutils 2.21, but for the sake of the system compiler or some building GCC from scratch, can one of you guys approve Steven's patch for HEAD, 4.6 and 4.5?

I really thought I already approved this patch when Steve pinged me (off-list) in Feb. Approved. -Loren On Sat, Apr 2, 2011 at 6:41 PM, Gerald Pfeifer <gerald@pfeifer.com> wrote: > On Mon, 21 Feb 2011, Richard Guenther wrote: >>> 2011-02-20 Steven G.
