OK, I’ll try. > What you should do is make system-linux-m68k.ads a clone of e.g. I’ve cloned system.ads and made changes while looking at i386, mipseb, armeb and macppc – let’s see how it goes from there. > system-linux-ppc.ads (both big-endian 32-bitters), set the ZCX variables to > false, and disable stack check probes.

Will do if that fails. Thanks for the ideas. > (I can't post a patch due to delays at the FSF wrt my employer's disclaimer.) That’s luckily no problem for me, I have papers with the FSF standing, even explicitly for GCC already.
