Well, avr-libc started on a family of cpus which will ever be to small to run
RTEMS and they started to implement a micro-libc catering the demands of
OS-less implementations. Since then, the avr-family has grown making it more
likely to be able to run "real OSes" on avrs.

Since then, they have been tieing avr-gcc closely to avr-libc and have been
ignoring the fact that their might be alternatives to avr-libc, repeatly
shifting RTEMS into positions of having to "catch up and cleanup".

I don't know if this is just unawareness or politics - I think it's the latter.

Demands from the user-side, probably are just "user unawareness" about avr-libc
being a proprietary/avr-exclusive libc. The issues RTEMS has probably caused by
us not having tracked the avr-gcc developments closely enough.
