You need to have a GCC that has stack-smash-protector (SSP)
functionality. You can see if your GCC does by issuing the following
gcc -v

If your gcc has SSP built in, it will output something like this:
gcc version 3.3.4 20040623 (Gentoo Hardened Linux 3.3.4-r1,
ssp-3.3.2-2, pie-8.7.6)

The "ssp" and "pie" (Position-Independent Executable) are what you
want to see. During compilation you want to see something like
"fstack-protector" in the compilation output. You can Google for more
info, but those are the basics.

Grsecurity and PaX can be found here:

Those are patches for the Linux kernel and I highly recommend that you
read the info available on grsecurity's site. The "features" page has
quite a list describing what grsecurity does:
