I've never heard this argument before. It does make some sense. It does have a flaw though. If the code was originally written for IA-32, and proven to meet timing constraints on the IA-32 host, then there is no guarantee that it will work on an IA-64 host. The timing analysis will all have to be redone. So perhaps the program has a valid reason for using extern inline, but it is still non-portable, which was the point I was trying to make. Jim
