nice idea,
after being completely lazy, and not wanting
to go through the mess, I finally did.
(nss just needs to know where the includes are)

flash plays, the stack protection triggers
flash crashes and burns, but firefox is still
there standing. clicking on back and then to another movie
(that's stack smashing free) does the trick.

maybe libc is set to sensitive, or flash needs the -fstack-protector
switch(Ill send libc a post to see
what they say).

Thanks for the help.
