Do you mean that it does not work with GCC 4.1.1?

I was somehow suspecting that gnat1 supports both ZCX and SJLJ, looks in system.ads, and decides what kind of assembly code it needs to emit based on that. Am I correct? In that case, I need just one compiler and two libgnats, right? Thanks for the input! -- Ludovic Brenta.
