I can't remeber me using any special linker switches and longs were definitely 64 bits. And sizeof(long)!=sizeof(int) is what's now causing problems on IA64 (XView basically treats everything as longs, and pointers happen to fit in there). I guess the main difference is the fact that the Alpha ABI guarantees that if the caller passes an int but the callee expects a long, then the upper 32 bits of the long are properly sign- or zero-extended. On IA64, they're undefined. :-( But hacking gcc is definitely not something I'm prepared to do just to make XView work... Martin
