Formally no, de-facto yes.

The FSF gcc-4.4.x release series is dead upstream, so there will not be 
any official FSF updates or bugfixes.

  The RTEMS-gcc/newlib patches are 100% API-locked and effectively 
"frozen". They will only see changes to really critical and non-API 
breaking bugs.

Which? I am not aware of any.

Sorry, I don't know which changes you have applied to your local fork of

As I tried to express several times before: I do not support Ubuntu.
It's already extraordingarily difficult for me to continue supporting 
the RPM-based Linux distros, but magnitudes more to support Ubuntu.

Feel free to use Ubuntu, but please understand that you're basically on 
your own.

I regret, but I have no idea what you are referreing to.
