Pat Volkerding rebuilt the gcc 4.5.1 packages for Slackware-current, adding support for LTO (Link Time Optimization). Apparently that feature was requested a lot.

Consequently I have rebuilt my multilib versions of the gcc-4.5.1 packages for Slackware64-current; get them at http://slackware.com/~alien/multilib/current/ (mirror site: http://taper.alienbase.nl/mirrors/people/alien/multilib/current/).
