The last I heard on the gcc development list was that DJ Delorie and
Nick Clifton (both Redhat) are officially appointed as gcc maintainers
for the port, and checked in support on 12/09/2013.  I guess that means
it will be released with gcc 4.9 - but it should be fine as an example
for the OP's use.

I don't know how much of the gcc port was changed when Red Hat took it
over (with TI paying the bills) and moved it in-tree.  Some of it had to
be changed or re-written due to copyright issues.  I know that a lot of
the library and support code was re-done, and I think this is based on
newlib-nano.  First priority is obviously for C, followed by basic C++
(typically without exceptions, RTTI, and limited library support - but
that's what embedded users generally want anyway).  I can't say anything
concrete about the state of Ada, but my guess is that the code
generation will work but the library will be limited.
