3.3.3 release notes [first draft]

[Joe Buck <Joe dot Buck at synopsys dot COM>]

Here is the first draft of the bug fix list for 3.3.3.  Please let me
know about any errors and omissions; suggestions for improved descriptions
of bugs are also welcome.

GCC 3.3.3 has not yet been released, but will go out Real Soon Now.

The list will be converted to HTML (I have a Perl script to do most of the
work, but it then requires a bit of hand-tweaking of the output) and will
be added to http://gcc.gnu.org/gcc-3.3/changes.html .

I need to clarify the status of preprocessor/13046; is it in 3.3.3 or not?

---------------------------------------------------------------------------

This document lists the problem reports (PRs) from GCC's bug tracking
system (Bugzilla) that are known to be fixed in the 3.3.3 release. This
list might not be complete (that is, it is possible that some PRs
that have been fixed are not listed here).

3.3.3 is a bug fix release only; there are no new features that were not
present in GCC 3.3.2.  The only exceptions are minor changes in the C++
standard library that implement the decisions the ISO C++ standards
committee has made concerning several defect reports (60, 63, 292, 300,
328).  Object code and libraries are believed to be fully binary
compatible with code and libraries from previous GCC 3.3.x releases
(though, as always, free software developers cannot provide any
warranties).

To see details of any bug, visit http://gcc.gnu.org/PR##### , where the
##### is replaced by the actual bug number.

Here is the list of fixes with respect to GCC 3.3.2:
