Re: [PATCH] support ptrdiff_t if it has the same storage size as int, but does not alias it

I know this message isn't remotely about the topic at hand, but didn't 
know how else to handle this. My name is Jennifer Whisenant. I am the 
daughter of Doyle Whisenant, who was a member of this group. He passed 
away on August 30, 2025. I accessed his email and found these group 
messages. I just wanted to inform everyone of his passing. Thank you for 
your time.
