The problem with that is that the error will still be enforced _after_ GCC would change the behavior of sizeof(aparam). Admittedly, I could write configure checks to determine if I have a version of GCC where sizeof(aparam) is bad and only enable the error there. > but there is nothing wrong about using sizeof on function > argument with array type if you know what you're doing, I have doubts here.

I don't want to enforce it if there's a single line of code that's using sizeof(aparam) for a legitimate purpose. But is there? Or can it be? Have a lovely day!
