Even the 2018 edition of POSIX does not require support for int64_t. As
I understand it, this was a concession to microcontrollers and Unisys
mainframes that are unlikely targets for Emacs (and are on their way out
anyway); still, it doesn't hurt to follow the standard when it's easy to
do so, as is the case here. Admittedly the portability change was
low-priority, but it made the source code smaller and simpler and it
used static rather than dynamic checking for some features, so I don't
see how it made Emacs "worse".
