Those pages have a long history, and I confess to not understanding
all of the details of the history. Looking more closely at the pages,
I think they are good enough. Let's leave them alone. (I did apply one
patch just now.)

Thinking about it further, I don't think it's necessary to document
loff_t in system_data_types(7). No APIs in the current glibc headers
even use loff_t, as far as I can see. I'm not sure that 'off64_t'
really needs documenting there either.

Thanks,

Michael
