Okay, that's good to know. Apparently their 'struct stat' is just
completely unusable from userspace without conversion because the
types are wrong. This is also going to lead to a nasty hidden Y2038
bug where the system looks Y2038-ready but the kernel returns
truncated file timestamps. Fixing dynamic-linked programs will be easy
(just upgrade to use whatever new syscall the kernel adds) but
for static-linked ones the bug will remain buried until it blows up..
(unless you use strace to check for it)
