It's transparent. If you build an application using the 1.5.x headers and libs, the affected types like off_t or fpos_t are 64 bit types automagically. The same goes for uid_t/gid_t becoming 32 bit instead of 16 bit. To quote a mail I've sent to the cygwin-apps ML a month ago: [...] please note that the new datatypes are used automatically. There isn't any choice between e.g. a off_t with 32 bit and a off64_t with 64 bit and no corresponding functions as stat and stat64. Building under 1.5.0 means, off_t is 64 bit now. stat is expecting a struct stat with 64 bit off_t. Full stop. No compile time options. All or nothing. Well, you got the idea, I guess...
