     Hi Marco!

   Actually, the typeinfo stuff is now fixed.  I stopped working for a while 
in order to get some (as I saw) critical bugfixes installed in upstream GCC 
before 4.5 gets branched.  I'm working back at it now; the typeinfo issues are 
resolved, but I've run into a hideous tangle trying to fix some GNAT 
regressions which have cropped up in recent builds.  (GNAT doesn't understand 
--program-suffix, meaning that during a bootstrap it sometimes finds the old 
gcc-3 gnat tools and sometimes finds the newly-built tools, and hilarity 
results when one of the newly built tools like gnatmake ends up invoking the 
old gcc-3 gnat1 sub-executable.)

   Since GNAT support isn't something I get an awful lot of traffic about, 
it's a lower priority, and I might just punt for the sake of getting a test 
release out.  I'll think about doing that if it looks like taking more than a 
couple of days.

   The only other thing I need to do before releasing it is ask for a bit of 
review/advice on the (substantial) packaging changes I'm going to be making, 
just to make sure I don't balls it all up.  I'll post about that separately 
later tonight.

     cheers,
       DaveK
