A #PHP global constant redefinition is a simple warning.

A #PHP class constant redefinition is a full Fatal Error.

I am so used to the Fatal error, that I expected the global constant to behave the same. Shouldn't they?

@pollita Yes, I suspect backward compatibility.

Now, I'd like to run some SCA check to spot such problems, and see how it can be fixed (automatically? manually?).

That way, it might help everyone.
