This See my notes at <https://sourceware.org/pipermail/libc-alpha/2019-January/100410.html> on what would be involved in changing the default *just of _FILE_OFFSET_BITS* for user programs, depending on whether the mode used to build glibc tests is also changed (but without changing the settings used for building glibc itself, which is much more complicated). -- Joseph S.
