If they aren't ABI compatible, no one is going to fix it. So documenting them as incompatible seems reasonable. >Also, aren't 3.0/ia64 and 3.0.1/ia64 binary compatible too (no idea, just >wondering)? 3.0 has ia64_app_header, 3.0.1 does not. Thus you can get undefined references to ia64_app_header if you mix them. I think the failure case would be building a shared library with 3.0 that imports functions from libgcc, and then linking it into a 3.0.1 compiled application. Jim
