		* configure		Add --enable-esp.  Add-fno-stack-protector
		to stage1_cflags.
		* gcc/configure		Add --enable-esp. Check -z now and -z relro.
		Define ENABLE_ESP.
		Check if we support crtbeginP and define ENABLE_CRTBEGINP.
		* libmudflap/configure		Add AC_SUBST enable_esp.

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.

Thank you all:

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.

For those w/out git access, this URL should help you:

It should be pretty easy to find your way around, you're a big boy after all.
