If it does, I still don't see how it could. Applications cannot
declare objects of type FILE, only FILE *. Short of some macros that
poke at the early members of the structure (getc/putc macros), it's
purely an opaque type, so changes to its size or layout (beyond said
early members) should not break ABI. If you claim it does, please
explain how you think it does, because the rest of us are missing that
