FWIW, it is still in somewhat-wide use for embedded purposes.  In
addition to being used by some 'random' embedded toolchains, IIRC
VxWorks also uses it for 64-bit MIPS platforms right now.

I seem to recall that some people have also attempted to use it to get
64-bit-ish userland (incl. shlibs) for some open-source unix-like
OSes.  (That makes me ... sad.  8-)


That doesn't mean that it's a good idea.  Just saying that it is, in
fact, still fairly widely used.
