I reported on the RISC/os experience. It wasn't so much that it
took too much time, but rather that it was hard to support on the SVR3
kernel interface, due to the messy definition of the streams interface
at the system call level. It is much easier if you can assume only
dynamically linked binaries, as in SVR4, and you can do much (although
not all) of the work in user mode, and much of the rest of the work
can happen as a side-effect of copyin/copyout.

That is clearly more expedient than trying to do bi-endian binary
support. Once the source-level endian issues are resolved (and most
should already be resolved in any GNU sources), having both litte-
and big-endian binaries and file systems is fairly simple.
