Portability should be achieved by using unified syscalls, which both the
diet libc and uClibc now use.  That saves space over the unistd.h
approach.

I think I can speak for both Erik and myself when I say that we don't
hate architectures and because of that don't support them.  If we get a
chance (and maybe a little help from someone who knows those platform),
we will port our libc to that platform.

Sadly, I don't have the deep pockets to buy myself a hardware lab with a
VAX to port my libc to it.  So I (and Erik, too, obviously) would need
at least an account on one of those boxes, with gcc, binutils, strace
and gdb installed.

In my eyes that is a waste of time, really.
But it's your time, so don't let that stand in your way ;)
