GCC 4.0.1 Status (2005-06-13)

[Mark Mitchell]

Those who have been watching carefully will note that there is no sign 
of an actual 4.0.1 release.

There are two blocking issues at the moment:

1. Benjamin Kosnik reports that there are ABI and/or version-symbol 
problems between 3.4.x and 4.0.x version of libstdc++, and is trying to 
sort out a solution.

2. Jakub Jelinek reports that we're miscompiling GLIBC.

The latter problem seems to me to be as severe as the KDE bug that was 
the impetus for this release.  The libstdc++ problem also seems serious. 
  In particular, Benjamin reports a mangling change that sounds like 
something that should perhaps have been controlled by -fabi-version, but 
I have not received a test case for that problem.

(I should confess that I am so skeptical about the likelihood that we 
have maintained full libstdc++ compatibility anyhow that I am not 
entirely convinced that we are not just seeing one of several problems...)

We're in a holding pattern (branch frozen) until we resolve these issues.
