+ ;; Some platforms don't use a 32-bit off_t by default, and thus can't
+ ;; handle files larger than 2GB. This feature will control whether

+ ;; 64-bit off_t. The intent is for this feature to be automatically
+ ;; enabled by make-config.sh on platforms where it's needed and known
+ ;; to work, you shouldn't be enabling it manually. You might however
+ ;; want to disable it, if you need to pass file descriptors to
+ ;; foreign code that uses a 32-bit off_t.
