See section 2.3.4 FSF releases and (now outdated) Appendix B. You will
see that the GCC 4.3 you are using is roughly equivalent to GNAT GPL
2007; Debian testing has GCC 4.4 which is roughly equivalent to GNAT GPL
2008.  Note that I backport some bug fixes into the Debian version of
GCC.

"known fixed" to whom?

The bug database at AdaCore is private (and with good reason).  If you
use the FSF version of GNAT, you should use the corresponding bug
database: Debian, Fedora or GCC upstream.

There are a few contributors external to AdaCore that provide bug fixes
into the FSF GCC, sometimes ahead of AdaCore; I normally backport such
fixes into the Debian version.  Eventually, all bug fixes end up in both
GNAT Pro/GPL and in FSF GCC.  The keyword is "eventually"; the time lag
can be months or years as you noted.
