I've done it before (for the Catamount OS on the Cray XT) and we (Sandia)
are in the process of doing it again (for Kitten, our latest lightweight
OS), but those are "mostly POSIX", as in there's still most of the
standard C library, but features like sockets, complex I/O, and standard
file I/O are missing. So the first question is how non-POSIX are you? Do
you provide the standard C library?
Feel free to follow up either on the list or in private if you want to
have a more detailed discussion about the issues we've run into.
