No, I haven't. I'd be perfectly happy with what we have plus a few bug
fixes, but the Library team wants to always use 'official'
releases. We don't use the svn tree for GCC on the standalone stuff
either. We always use an fsf release tarball. (plus maybe some local
patches for arm that haven't made it into the gcc tree yet.)
