Not sure if it got lost, so I'm gonna summarize what I said earlier,
Why not have /compat/linux32, and /compat/linux64 (For things that
require one or the other), then just have /compat/linux linked to the
native setup for the machine? That gives the ease of /compat/linux for
the native stuff, without causing the problems Andreas pointed out.
Also allows people with "clean" 64-bit friendly code to just use
/compat/linux on AMD64 or i386, and have things work in whatever way
is native to the machine.
This could also be extended to other archs, if that ever becomes an
issue. (linuxppc, linuxsparc64, whatever), with linux still pointing
