gcc 3.3 release notes addendum: Ada bugs were missing

[Joe Buck]

The 3.3 release notes I posted left out Ada bug fixes.  Here's a summary
of the significant ones (I'm omitting the documentation and copyright
fixes).

ICE's:

8358 (ada) Ada compiler accesses freed memory, crashes

Ada compiler and library:

6767 make gnatlib-shared fails on -laddr2line
9911 gnatmake fails to link when GCC configured with --with-sjlj-exceptions=yes
10020 Can't bootstrap gcc on AIX with Ada enabled
10546 Ada tasking not working on Red Hat 9</li>

I'll be sending a patch to add these to the web page.
