You evidently think about systems where libc is a single shared
library, and the _only_ library used by Emacs where the 32-bit time_t
type is used. Think more generally: what if some of what you consider
'libc' was linked statically into Emacs, and what if some of the other
libraries Emacs uses use 32-bit time type?

That is not necessarily so.
