Thanks for your reply. I haven't looked for PaX issues yet (I suppose
it'd be at runtime), I'd like to achieve firstly a successful
compilation using PIC. I've played a little with the inline asm code and
I think it can be done. Did you tested those PaX issues using a provided
binary or you compiled from source code? Can you tell if the binary you
tested had PIC enabled?

regards,

Dariem
