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?
