If you really want GCPROs, you could write a GCC plugin to verify that they are in all the right places. This would work for all the code that isn't platform-specific anyway. Writing a GCC plugin to do custom checks like this is pretty easy nowadays, you could do it in less than a day. I tend to think that GCPRO is worse than conservative marking. What advantage does GCPRO have? Tom
