third draft, 3.0.3 bug fix list

[Joe Buck <jbuck at synopsys dot COM>]

Here's a third draft, which will be the last one I have time to do this
year.  I'm running out of time before the holidays (I'll be traveling
next week), so I won't have time to put anything on the web until the
new year.  But if anyone finds this data useful to go out with the
release announcement, feel free (3.0.3 still hasn't been officially
announced!).  Clearly 3.0.3 fixes lots of bugs, so congrats to all
who helped.

Thanks to Richard Henderson for some more reports, I also found another
couple in GNATS that I added.
-------------------------------------------------------------------
Here is a list of bugs that appeared in earlier 3.0.x releases and that
are fixed by the 3.0.3 release.  There are undoubtedly a few fixes that I
have missed.

The number in the first column gives the GNATS problem report number, or
"****" if there is no known GNATS report for the bug.  In many cases there
were duplicate GNATS reports for the same bugs, in particular 4763 and
4529 have large numbers of duplicates filed.
