I said:

========================================================================
Tools included:

Full GPL:
  ASIS, AUnit, GDB, GNATColl, and GPRbuild from GNAT GPL 2014.

GPL with Runtime Library Exception[1]:
  XMLAda from the public SVN repository[2] at revision 233185
    (XMLAda-SVN for short).
  AWS from the public git repository[3] at commit
    e0d260e2d5dbbd93577949307935848de2390818 (AWS-git for short).
========================================================================

Of these the only libraries you're likely to use in your own code are

GPL: ASIS, GNATColl

GPL with RTLE: XMLAda, AWS 

> 2) Is the Ada95 compiler in GCC 4.9 also improved?

It's an Ada 2012 compiler, which can be made to work in Ada 2005 mode by
-gnat2005 or -gnat05, in Ada 95 mode by -gnat95, and (to some extent) in
Ada 83 mode by -gnat83.

The (possibly incomplete) list of PRs fixed[1] in 4.9.1 vs 4.9.0 doesn't
show any Ada-related bugs, so I guess nothing major (mind you, the Ada
maintainers don't curate the Ada-related bugs very well). One would have
to check the svn repo to be sure what Ada-related changes, if any, there
actually were.
