I think this is a quite silly argument. $ find /usr/src/sys -name \*.[ch] -a -type f \ | xargs grep int[0-9][0-9]_t | wc -l 37026 I think that shows we can depend on int64_t existing and usable. > fts(3) is a purely userland library which need not depend on a > particular platform[1], so I did my best to avoid any assumptions like, > `There will never be a 96-bit system around.' This is FreeBSD - not a magazine on C programming, in which examples should be usable on all platforms. Given the use of intN_t in the kernel, we already cannot boot on this future platform Please don't un-C99 the system that folks have worked to update us to. -- -- David (obrien@FreeBSD.org)
