GCC 4.9.0 should be released in a few months from now, possibly in March
2014. It is already available in experimental and Matthias Klose is
actively working on it. Apparently[1] he intends to make GCC 4.9 the

I have just created the branch org.debian.gnat-4.9 in monotone and I
propose the following plan:
- starting right now, everyone interested (and in particular the
maintainers I talked to at FOSDEM: you know who you are!) works hard
on updating all the Debian patches for gnat-4.9; this is the top
priority.
- at the end of March 2013 (two months from now), we review the state of
gnat-4.9: is upstream GCC 4.9.0 released? Is it in unstable? Are we
satisfied with the quality and stability of gnat-4.9? and we make the
final decision as for the Ada compiler for Jessie.
- Immediately after this decision is made, we update all other packages
to the chosen new compiler, starting with ASIS and PolyORB.
The obvious risk with this plan is that, if gnat-4.9 turns out not to be
viable, we'll have wasted two precious months for the big transition.
