List of important PRs for 3.3.1

Tue Jun 17 22:38:00 GMT 2003

OK, here's a list of what I think are the 66 most important PRs out of
the 134 that have the 3.3.1 milestone set. I'm not an expert in the
"target" field, so have been more generous in including PRs in this
area than, say, in the C++ category.

All other reports are, in my opinion uninteresting (ICE after error),
or not important and may be fixed later (documentation, obscure
feature, etc). 

It would be nice if the respective maintainers of these parts of the compiler 
took a look, and if possible work to reduce the length of the list. If you 
feel that a bug cannot be fixed in the timeframe for 3.3.1 (or any other 
3.3.x release), please bump the milestone to whatever you think is 
reasonable.

Mark, feel free to use the list for whatever purposes. Joe, I don't know how 
you generate the lists of fixed bugs, maybe this is of help to you somehow.
