I doubt if binary compatibility with GNU/Linux is a good thing to
have. It looks like we are then bound to the ABI and can't change it
if we want to keep compatibility. There are also other problems, for
example a program compiled on GNU/Linux could happily use PATH_MAX but
that would cause a buffer overflow on GNU/Hurd. Also programs on
GNU/Linux can use the /proc filesystem and can't on GNU/Hurd. There
are probably more issues.
