+This work started with bugs #94325 #100689 #106222 #149292 #149649 and the overlay on http://overlays.gentoo.org/dev/kevquinn.
+By Kevin K. Quinn, Peter S. Mazinger, Natanael Copa, Alexander Gabert, Solar, PaX Team, SpanKY and mentor.
+
+The work stalled. Some threads on the Gentoo forum started to do their own fixes to get it working.
+Xake started the thread where most of the new work is done: "How long until hardened and toolchain will produce a hardened gcc4?"
+http://forums.gentoo.org/viewtopic-t-668885.html. I joined the thread and started to code.
+
+We started with the pieworld code from kevquinn's overlay. The PIE and minispecs part hit the tree later on.
+With GCC 4.4.0 I was willing to do some code cleanup, use built-in specs and add it as --enable-esp in the
+configure command line.
+

+
+Gentoo patchsets that have grown too large to keep on the rsync mirrors have
+been moved to our git tree. From there, we bundle up all the whee little
+patches into a tarball and distribute it via our public mirroring system.
+
+If you want specific info about a patch (like wtf it does or whose great idea
+it was to change the code), read the patch ! We try to fill out the top of
+them with useful info such as what it does, why it's needed, bug reports,
+original creators, etc... For simple patches, we reserve the right to assume
+your IQ is greater than absolute 0 and figure out what it does w/out an
+explanation. If, by some miracle of science, it falls below the absolute 0
+mark, you should help mankind by finding some scientists and letting them
+probe you with their ... erm ... probes.
