How do I do that for ALL the programs to be compiled without having to go to
modify ALL the Makefiles?

Maybe writing a bash script named /usr/bin/gcc that contains just "gcc
-fno-stack-protector"?

For me, problem was fixed by using gcc-3.4 instead of gcc-4.0 (both installed,
with gcc as a link to gcc-3.4).

Is it worse than the solution you found?

I'm a biologist, so apologize if questions are too simple.

Thanks,

Javier.
